Am acquiring some data, and I need an answer..
who wins between the two hokage candidate?
And who wins in a fight?
Naruto would be the better Hokage since he wants it more while Kakashi doesn't and Naruto have people backing him up. Shikamaru said Naruto isn't that smart like Hashirama and unlike Hashirama who had Tobirama to advise him, Naruto doesn't have a brother so Shikamaru will be there for Naruto. Kakashi himself said he will make sure Naruto doesn't failed because he will be there for him. Naruto us highly acknowledged by the alliance, the 5 Kages, and the Edo Kages so he have everyone who are willing to help him as he helped them. Also the current generation was said to take over things now so having Kakashi take over wouldn't let the current generation take over.
Kakashi, Naruto is still growing physically and mentally and is only 16 years of age. He may be brilliant on the battlefield but how he currently is, hes not ready to run a village. Once he matures more than sure he will make a great hokage, but as of now, Kakashi is more likely to be the 6th over Naruto. With the new movie coming out which looks a couple years forward, Naruto still isn't Hokage so the current is either still Tsunade or currently Kakashi. As of now, Kakashi is the best choice.
Naruto is 17, his bday was during the war

Also Hiruzen and Gaara both became Hokage young themselves and Naruto will have Shikamaru as an advisor, have Kakashi backing him up (he told Obito this when he and Minato were talking to him), Have Sakura to help him when she already helped Tsunade with errands.
Kakashi is definitely the better choice for Hokage.
As for a fight, I know people are automatically gonna say Naruto but think about it for a second. We're talking about Kakashi who has been watching Naruto fight this entire time and knows his student pretty damn well, he's seen him pull out a lot of tricks. We also know that Kakashi isn't just PS and Double Kamui, he's damn clever and has an arsenal that can easily catch Naruto off guard at times. With Kamui snipes (one that works faster thanks to having both eyes) and being able to go intangible, plus a Susano'o to stave Naruto off at times, defense is covered. Speed isn't a factor here since Kakashi has been able to stop multiple attacks from Kaguya and react well, he even managed a good hit on her. Naruto has better striking speed than Kaguya but with Susano'o, intangibility, and Kakashi's reflexes lately, that's a small factor. And at any opening, Kamui snipe is GG. Current Kakashi is essentially him, Obito and Sasuke all in one.
So in a fight, I say Kakashi beats Naruto high-extreme high diff. I see Kakashi winning more than I see Naruto winning.
It doesn't matter if Kakashi was watching Naruto fight this whole time, Kakashi calls Naruto the number 1 most unpredictable ninja and Naruto shows this in the fight with Kaguya as he does in many of his fights that allowed him to beat people stronger than him in past fights. Naruto is the one more to catch Kakashi off guard, Naruto have his Bijuus also helping him in strategies and we seen Naruto switch place with Yang Kurama so what's stopping Naruto from making 9 clones and having each Bijuu take over a clone which would have Kakashi fighting 10 different fighting styles. Kamui snipe does not work faster with both eyes, Obito was using his Kamui to warp himself and Kakashi used hi to speed up Obito's Kamui so Madara couldn't kill him before he revived Naruto.
Also go back some chapters and you'll see where Kakashi tells Minato that he was going blind in his left eye and that he needed to be very close to use Kamui so he's not Kamui sniping anyone mid range or long range sicne he needed Gaara to take him right up to Madara's shield to use Kamui. Also Kakashi react to fast movements, it's easier to read if they move in a linear movement as Sasuke pointed out when Bee 3 tails was faster than him but he overall needed Karin to sense Bee's movements and Sasuke speed is a bit higher than Kakashi's. Naruto's KM full speed is compared to Minato's FTG which is instant, Naruto speed now should be faster than KM and it's faster than Kaguya could react to and he can react to Kaguya speed as well.
Naruto is also a sensor who evaded Limbo without even knowing about Limbo, Kakashi's doesn't have reflexes to react to Naruto except to go intangible. Oh and since Kakashi's left eye is going blind he will be losing his left eye (Kamui snipe) and PS and will only have Obito's Kamui. But Naruto knows that Kakashi have to be tangible to attack so this is where his clones overwhelm Kakashi with chakra arms oh and lets not forget Naruto's chakra orbs/blades can capture Limbos which are in a different plain so what's stopping that from happening to intangible Kakashi?
Exhaustion isn't a factor here. Kakashi is already fighting exhausting and he's handling himself keeping up with the speed of combat right now. At the beginning of a fight, we're talking two character fresh off the bat, we can't considered them weakened like they are now. Meaning Kakashi with Rikudou chakra in him isn't losing steam soon since just Kyuubi chakra keeps him going on for a while.
As for the clone combo, we know that Naruto's clones usually don't move as fast as the original with no clones could move. Meaning Naruto isn't gonna be blitzing like he did to Kaguya, it'll be at a slower pace so Kakashi should be able to keep up since he's been able to react to Kaguya multiple times. While Naruto asked Sasuke to save Sakura with his S/T, Kakashi was able to get there quick enough to save her. And people say Naruto's speed > Sasuke's S/T but when neither were confident that they help Sakura from Kaguya's attack (which someone noted was fast), Kakashi managed to pull it off, meaning he more than has the reactions to keep up with some clone spammage and even a normal Naruto blitz since he can go intangible.
Yes exhaustion is a factor here, it's a major factor. Kakashi is not exhausted, or was not fighting exhausted. Kakashi was doing nothing at all since after Kakashi used Kamui on Madara's shield, Kakashi have not been using his chakra or fighting so he's been resting until a few chapters ago when he and Obito ran to protect Sasuke and Naruto so Kakashi was well rested before he got Obito's chakra. You do know Naruto have been in intense training before entering the war where he made 12 clones (each with 1/13th the power) and fought on all battlefields and he does feel an amount of each clone exhaustion and his first break was when Sakura was healing him the 2x she healed him and when he was dead. Kakashi did have time to rest in the war, they rested but was on guard at nights, he was in the background when Naruto and others were fighting, he was laying down resting and stitching himself up in Kamui dimension, and he was recovering after he Kamui Madara's shield.
Kakashi who was rested before getting the Sharingans is falling with his eyes closed after using his PS and Kamuis

. In a battle you shouldn't close your eyes until you know it's over unless you're that exhausted. Naruto clones can blitz Kakashi pretty easily, You're basing that oof of Tobirama saying clones are a bit slower than the real thing but that doesn't mean they still can't blitz someone who speed is close to Sasuke's speed and we saw how Sasuke speed measure up against A's speed so even is Naruto's clones are slower than him, they will still be faster than Kakashi can react other than Kamui (intangible). Kakashi doesn't have the stamina to last long, he will be using up all of the chakra since Kamui and PS takes a lot of chakra and he is not a Senju or Uchiha lineage so he wouldn't have the large stamina or powerful chakra they have and he's not going to have a lot of Sage chakra which is the leftover of Obito's chakra and we know he was nearly out by the time he died. Kakashi was standing closer to Sakura and that part was only made to showcase Kakashi but his speed and reaction are far below Naruto and Sasuke's.
I kept all that in mind sir, and despite saying how well I thought Kakashi countered Naruto, I still went with high-extreme diff. Shouldn't that tell you something?
Anyways, despite Naruto keeping Kaguya on her toes, he hasn't been able to defeat her until just now and that's with everyone's help. Alone, he couldn't do much to make any real progress with her. Chakra punches aren't an issue when you and your Susano'o can go intangible. Naruto knows Kamui's weakness but Kakashi knows that as well. He won't use it as carelessly as Obito might. I say he does have great stamina since he has Rikudou chakra within him. Naruto is a great fighter himself but please don't use that reference of the beginning of pt 2. That was a Kakashi obsessed with finishing his book Lol But this one isn't :| Meaning Kakashi isn't about to get fooled so easily. But upon getting tricked (which could happen a couple of times), all Kakashi has to do is go intangible and with the battle experience Kakashi has gathered over the years, that's not far-fetched at all.
Well we never seen Naruto serious until he was when he speed blitz her and threw all of those Bijuu RS at her which sent her in an unstable form. Kakashi's Susanoo can't go intangible, that's why his Susanoo cracked while he went Intangible. Trying to make his Susanoo go intangible would burn Kakashi out in 1 go as he fail to do so. Kakashi and Naruto do not know about the 5 min limit so Kakashi could be forced to use it that long and it cancel out and he can die that way. Obito never used it carelessly, he used it better and more efficiently than Kakashi, heck when he got his left eye he was using it better than Kakashi as well even when it was going blind (using it to go to other dimensions).
Kakashi can't use the Sharingan as well as a true Uchiha and Obito only had a little bit of chakra when he died so Kakashi did not have that much chakra of the Sage, you're thinking it's like Sasuke and Naruto's when it's much less. Obito took a small amount from Madara which he have been using to find Sasuke with Sakura and Save Kakashi from Kaguya's bone. Kakashi calls Naruto unpredictable so he can surprise Kakashi pretty well. Kakashi has to be tangible to attack, Naruto can fool him by having him attack a clone then attack him in turn. Naruto has speed, the best Sensory ability, power, endurance, reaction, unpredictability, stamina, physical strength, durability, and 9 Bijuus to aid him with power and smarts. We also haven't even seen Naruto's full power like his avatar mode.
