I don't know about Sasuke but I know Naruto didn't use his most powerful techniques and why would he when if he did would probably not end up well for Sasuke.It does not matter regarding the fight itself. The fight itself was a draw, they both used their most powerful techniques fully loaded with bijuu and nature chakra, it was a draw. From then on, it was their own skill against each other, and the both of them were struggling to stand even, and sasuke was still not totally used to his rinnigan as kurama stated.
So techinically, if sasuke was used to the rinnigan, he would have won, according to kurama, but let's not go there, I don't want to make you mad that ultimately it was plot that it was a draw between them.
Naruto won the morality, they both tied in battle. So some of you with that banner don't realize what you all are really saying, which is what makes a lot of us laugh, because I remember a time when these itachi fanboys insisted on here in 2012 that itachi > nagato for so and so reasons, but a lot of us knew it wasn't true, and now the databook is clearing that up. If you truly believe naruto > Sasuke, you are just as dumb as the itachi > Nagato fans. Sorry man, but that's just how it is.
They both are just as beat up, both are dying, both used the best techs against one another, it's over. Neither of them are stronger, they have techniques they are better at then the other yes, but they even it all out like yin and yang, quite literally. Susanoo = yin, kurama mode = yang. The bro fist done within those two forms is obvious enough of a reference of two equals battling it out alone.
Doesn't that make you stupid like Itachi vs Nagato fans when you pretty much just stated that Sasuke Mastered Rinnegan > Naruto.
Naruto does want to beat Sasuke but not the Sasuke he fought at VotE 2 to which he pretty much stated himself.
Like I already said Naruto withheld certain techniques against Sasuke so did not go full out with his most powerful techniques so you're wrong in assuming this at least when your refering to Naruto.
I realize fully of what I done when I put that signature in my profile so no need to assume I don't understand why I used it in that case.
