First of all, VolatileSoul, I thank you for being up for a good debate. I'll answer accordingly to each of your statements.
First of all, I'll apologize in advance since it seems my statements were left a little bad explained, since it seems like you misunderstood some of my points, or you didn't understand them at their fullest. I'll elaborate a little more.
No where is it ever stated that Uchiha don't have the capacity for large amounts of chakra. Normal people like Gai have insane amounts of chakra despite being an ordinary person. Chakra levels are not set. They increase the more you train you're body and gain experience. Madara himself destroys the notion that Uchiha don't have large chakra. The man fought for 24 hours against the Senju of all people.
R: Read chapter 462. The Elder Son of the Sage inherited his Spiritual Energy, his powerful eyes, and his powerful chakra. He didn't inherit the amount of Physical energy of the Sage (trait that was inherited by the Younger Son).
As we know from chapter 90, Chakra Reserves = Stamina = Physical + Spiritual Energy. And we also know from chapter 462 that the Uchiha comes from the Elder Son's bloodline, and this clan is very "pure blood" (this last statement isn't a fact itself but it's logic, since almost every Uchiha we know awakened the "Eyes").
So it's common sense to know that their chakra reserves are moderate, but powerful... because in the best of cases, even if they have the tremendous amount of spiritual energy of the Elder Son's bloodline, they don't wield the tremendous physical energy needed to balance that spiritual energy, to mold chakra.
The formulae from chapter 90 says Stamina (a.k.a. chakra reserves) = Spiritual + Physical Energy (not mixed).
And let me inform you that I took the bests of cases for the Uchiha Clan, because I'm saying that they got a decent amount of Physical Energy... I could say that they got a minimal amount of physical energy, meaning that their chakra reserves could be worse than a Jounin or chuunin ninja.
Also, it couldn't be possible for the Elder Son to get more physical energy from the Sage, because the son that got the most of Yang properties (described in chapter 510, being these the Physical Energy, and the Lifeforce/Vitality) was the Younger Son.
I don't recall spiritual energy needing life force to be made or the other way around.
R: Read chapter 462/510 and think how did the Bijuus got both Physical and Spiritual Energy from the sage and the Juubi.
The sage had to use his Lifeforce/Vitality and Imagination, plus the Juubi's chakra in order to create the nine beasts and the Mazou. It's a process described from the Technique of Creation of All Things... a common property of the Yin/Yang Release.
I'm not saying that Lifeforce alone can produce both of these energies... What I said is that Lifeforce AND Imagination is needed.
By the way: Don't get confused. Lifeforce and Stamina are two different things. If you want to learn about what is stamina, read chapter 90. Lifeforce is another different thing, it is not chakra by any means... it is a property, the capacity to give life/regeneration, and this is very well explained in chapter 510 (also referenced when Naruto awakened KCM, as "Yang Power").
Yin Chakra and Yang chakra are not the same as physical and spiritual energy. People like Gai, Ay, Sandaime Raikage and a host of others possess ridiculous amounts of chakra. All that is needed to make chakra is Spiritual and Physical energy. The more of these two energies you have, the more chakra you can make. Even Yin and Yang chakra are made from Physical and Spritual energy.
R: Agreed. Yin power and Yang power are not the same things as the Physical and Spiritual Energies "respectively". As I stated in my post, Spiritual and Physical Energies are the components that defines how much chakra reserves can be inside a shinobi. This is explained in chapter 90.
But in the other hand, Yin power says how strong is the shinobi's chakra and Yang power says how much vitality is emanated from the shinobi's chakra. Chapter 462 explains this very well.
But don't get confused about this conclusion... there is a connection between Yin + Yang and Spiritual + Physical Energies.
"Creation of All things" again. The user of the Yin/Yang Release uses their Yin and Yang powers to create a live being that holds both Spiritual and Physical Energy, so there is a way to put all these components and make a comparison. That's the way Bijuus were created.
Powerful chakra means the techniques themselves are more powerful. Having powerful chakra doesn't let you spam techniques. Itachi's chakra, despite being small, was extremely powerful. He also has better chakra control than Sasuke. Likely even know. Yet he cannot spam like Sasuke can. That "proof" actually disproves your point. Tobirama made it clear that the techniques had to have the same amount of chakra. There is no point disputing manga fact.
R:
Hirudora said:
Sasuke have normal stamina... but his chakra is powerful. Moreover, he got tremendous control over his own chakra due his training, Sasuke is an expert, meaning that he can use it efficiently, and as a plus he can use his EMS to use his chakra accurately without wasting any. Proof enough is how he was able to match the chakra ratio with Naruto's Rasenshuriken for their Shakuton combo.
I never said Sasuke was spamming his techniques in this topic. I said he was able to use them efficiently (a.k.a. less effort for greater effect), and can do it without wasting any. Ergo, what I'm saying that he, compared to shinobi that don't have better Yin power/Spiritual Energy, he can use just the same amount of chakra to deal more much more damage (or he can use way less chakra deal the same damage).
So, basically, you're just repeating what I said. Try to be careful when reading my statements, please.
We were never even shown those people. And unless you haven't noticed, the alliance has Naruto's chakra. They won't get tired anytime soon. And panting is not a sign of a lack of chakra. Naruto has panted many times before yet always pulls more techniques. It's the same with Sasuke. Panting after PS but then using Amaterasu.
I think you're not taking in account the most important thing about the fact you're stating... Yes, people have Naruto's chakra, but more importantly... was it like that from the start of the war, or just when they got in to confront Obito?
I'm talking about ALL the war. These shinobi have been fighting from 2 days, Naruto hasn't been more than one day giving chakra. So you're making a valid point from the second half of the war, but you're not viewing things with all perspective you could... you need to take in account the other side of the war that took place before the Juubi Revival's Arc.
No where is it even stated that Sasuke has limited chakra. You started with that axiom. You assumed that was the case and built you're argument around it. But as Onoki said, the chakra from PS is massive. The very fact that Sasuke abuses the Mangekyo, something noted for it's massive chakra cost, implies Sasuke has large amounts of chakra. Chakra control was never even hinted to be one of Sasuke's strong points. Itachi has insane chakra control which was better than Sasuke's yet he can't spam MS at all.
R: I shall recall to the first statements which I used to counter your rebuttal.
Read chapter 462. The Elder Son of the Sage inherited his Spiritual Energy, his powerful eyes, and his powerful chakra. He didn't inherit the amount of Physical energy of the Sage (trait that was inherited by the Younger Son).
As we know from chapter 90, Chakra Reserves = Stamina = Physical + Spiritual Energy. And we also know from chapter 462 that the Uchiha comes from the Elder Son's bloodline, and this clan is very "pure blood" (this last statement isn't a fact itself but it's logic, since almost every Uchiha we know awakened the "Eyes").
So it's common sense to know that their chakra reserves are moderate, but powerful... because in the best of cases, even if they have the tremendous amount of spiritual energy of the Elder Son's bloodline, they don't wield the tremendous physical energy needed to balance that spiritual energy, to mold chakra.
The formulae from chapter 90 says Stamina (a.k.a. chakra reserves) = Spiritual + Physical Energy (not mixed).
So as much Sasuke got a moderate amount of Physical Energy. He only exceeds in Spiritual Energy.
Madara chakra level isn't the baseline for huge reserves. You can have less and still have ridiculous amounts. He didn't use less chakra to do anything. You fail to realize that simply having good chakra control will not help you spit out large scale jutsu.
You fail to realize the requirements to increase Physical and Spiritual Energy (stamina) which are explained in chapter 17. Madara have been more time than Sasuke increasing his chakra reserves.
Also, you need to explain yourself. What is chakra level? Are you talking about quality (power) or quantity (reserves)?
For the bolded part... I partially agree. You need both chakra control and <great chakra reserves> OR (inclusive) <powerful chakra> in order to manifest a large scale jutsu.
Well, it's like using a pile of trucks with kerosene vs an uranium bomb... both could be equally powerful, but you would indeed need quite more giant trucks (huge chakra reserves) to achieve the same power of the little uranium bomb (moderate powerful chakra reserves).
He only used it for a bit of time because it was destroyed, not because he had stamina issues. Sasuke holding it for longer isn't far fetched by any means. Enton barely takes chakra as it is. He doesn't have to have a better body and mind. He doesn't have to have as much chakra as Madara to have large chakra reserves. You can have less chakra than someone and still have large reserves.
About Madara's PS being destroyed: Makes sense, fair enough.
Sasuke holding it for longer: It is farfetched unless you can explain a solution to this breach: The Quality/Endurance of the PS depends on how much chakra can the caster use to mantain it, and how much power (Spiritual Energy) can the user inject into the PS in order to make it resistant (since Susano'o is the manifestation of the user's chakra and mind, hinted by Karin in the Kage's Summit). If Sasuke doesn't have as much chakra as Madara does (meaning that he doesn't have as much Spiritual Energy as Madara does), how can his PS be active more time than Madara's PS? How can it be more resistant than Madara's PS? If Sasuke's PS can't be more powerful than Madara's PS right now, how do you expect from him to hold it more time, using it with an entire cape of enton covering it without the eyes pressure/bleeding drawback, knowing that also Sasuke doesn't hold as much experience as Madara? Can you explain that? I couldn't, that's why I find this possibility way farfetched. Also, Enton USES greats amount of chakra. The only reason Sasuke doesn't use a lot of chakra with Enton is because he has powerful chakra, and in consequence he doesn't need to waste a lot of this chakra to use this element efficiently, as I stated in my post. But that's only with enton in his little/medium size techniques... now imagine a PS entirely covered with Enton... that's the reason I countered this topic. I found this possibiility too farfetched.
Bolded: Were you trying to say "overall power"? Because it just sounded like a contradiction.
---
Summing it all... I'd recommend you to take a read on chapters 17, 90, 462 and 510. Almost all my logic plays around these chapters.
Also, let me clearify something... I'm not a hater or a fanboy (I only say this for the sake of sanity). Thanks again for your good points.
