Are you dumb? One of Naruto's many clones beat Muu and the 3rd Hokage who both were fighting to kill and being control by Kabuto. Naruto entered the war right after training and the manga haven't show Naruto resting at all. Naruto said himself he wasted a lot of chakra when he tried to transform into Kurama and when he was training to use tbb, he also said there's no time to rest... Naruto then made around 9-12 clones (splitting his chakra among them) yet one cloe was able to beat 2 powerful kages and now he's stronger. Naruto in KM is already faster than the 4th Raikage (fact) then he got faster in Bijuu Mode. The 4th Raikage is said to have bijuu level chakra (more than the other kage's) yet a tired Naruto in BM used a tbb that equal the power of 5 Bijuus. Now image how powerful a fully rested Naruto with no shadow clones spread thru out the batlefield would be, yeah I thought so. Stop being a fan boy, Naruto has the strongest of the 9 Bijuus with near limitless chakra.
Psst, it was the 3rd Raikage. xd
Anyway, I just personally don't see how Sasuke has a chance at this point.
Naruto trumps him in the following areas:
-Chakra (DUUUUHHHH....like by a hundred-fold)
-Speed: Uber; leapfrogged A at this point in both chakra Modes. Base Naruto was shown to be pretty fast post-Danzo fight, though likely slower than Sasuke. SM Naruto is definitely faster.
-Strength (Can move a Tailed Beast Ball...damn, 'nough said)
Intelligence, they're somewhat equal. stat wise, Sasuke's 3.5/5 idn't much above Naruto's 3/5. Naruto's intelligence is more in the from of cleverness and unpredictability, while Sasuke's seems more structural. So yeah, about even
-Ninjutsu: Not sure. Naruto has like a billion Rasengan variations that are all powerful, not to mention the godly Tailed Beast Ball, S-rank buzz saw that is Rasenshurkien and whatever his unknown "that technique" is. Sasuke has several Chidori variations which culminates into Kirin. Thing is, Kirin takes some preparation and given how fast Naruto is now, I doubt whether even it or Amaterasu can hit him. They
may be even here. It just depends on the extent of Naruto's new powers and whatever HAXes Sasuke's EMS will display. This category will absolutely be Sasuke's saving grace.
-Genjutsu: Useless against Naruto now, not much to say.
-Taijutsu: somewhat interesting. Naruto's defnitely improved and may be able to hold his own against Sasuke without the Sharingan (maybe). The Sharingan tips it back to Sasuke's to favor, but Frog Kata tips it back to Naruto's, since because Sharingan wielders tend to be effiecient with their evasions by barely avoiding attacks, they will fall prey to the natural energy, whoch cannot be seen by anyone not in Sage Mode, not even dojutsu wielders. Who knows.
