awesome post... lowl I to have to watch what I say due to the age factor...I voted for pain.
There have been made tousands of arguments for both sides already. Most of the people came to the conclusion that it will depend on fighting time, chakra and stamina. So we can't say for 100% sure.
Most of the arguments have been covered by facts from the manga or like the guy above from the narutowiki page. But be careful with narutowiki! Not everything there is true!! Like on the normal wikipedia page.
So there is one thing I would like to add. I rarely post on this forum. It seems that the overall age of a lot of people which post here regulary is 10 or even below. I am so tired of this sharingan, MS bla bla bla Uchiha Uchiha Uchiha....... For me Itachi is the only respectful sharingan user up to now. And I like his character. But have all the Itachi supporter forgotten about the BLINDNESS!!! Itachi was half blind already. Some of you think that Itachi can just spam MS jutsus without consequences. Yeah right. Someone said, that we saw how fast sasuke was going almost blind. And Itachi was using the MS far longer. So what about pain?? Is the user of the rinnegan going blind too?? The answer is no. So Itachi is handicaped before the fight even starts. The rinnegan is the most unique occular jutsu. The Sage of the six paths had the rinnegan too. And pain has more chakra too. In the end itachi would be blind or overexhausted!! With EMS it's a different story. It's hard to land attacks if you are half-blind or even blind isn't it?
So please stop overrating the MS! A power which makes you blind can't compete with the rinnegan! That's that.
with an epic post like this NB would see having you as an asset :hug:
whenever I use wiki I make sure I read through it so its correct and based only on the information form the manga... plus I was way to lazy to explain everything and needed references to back up my point of view... and the power to copy and paste was overwhelming...
now as for what you said... I do agree with what your saying... Itachi's blindness factor will be a handicap... but he had no problems dodging Sasukes shurikens... Itachi being as smart as he is would figure out all of the Pain's abilities...
but you have to admit Nagato using Pain and the jutsu's he does, must put a massive strain on his body... no?
we have only seen Nagato fight twice... and every time it seems to me that he is stringing himself... pushing himself to the limit... Itachi on the other hand is way to claim and cool... maybe basing my point of view on this factor I voted on Itachi...
Kishi has sure done an awesome job making these 2 character very likeable... I dont like Itachi more then Nagato... they both helped Naruto out... if anything Nagato was more an enemy to Naruto then Itachi...
win or lose I will vote for Itachi and always have his corner...
