But logic tells you it was a "draw"
No it doesn't...
Logic tells you Naruto won.
Let me explain, after the Rasengan/Chidori collision, Naruto was still conscious, Sasuke was knocked UNconscious, he had to wait for Sasuke to wake up, similar to the fight in part 1 where Sasuke was standing over Naruto's body.
Back in part one again, Naruto vs Gaara, Naruto won that fight.
In all of these fights, both parties are ****ed beyond belief, it's just one of them feels a little better than the other, that one won the fight.
Naruto vs Sasuke part 1 - Sasuke wins still conscious.
Naruto vs Gaara - Naruto wins because he can move with his chin, Gaara can't move.
Naruto vs Sasuke part 2 - Naruto wins because he's still conscious, Sasuke is asleep.
