the last post kinda caught me off guard... Let me rethink what I was going to say...
Oh yeah.
Doesn't the wind element beat the fire element? I forgot the diagram and such, but in terms of elemental energies, Naruto wins, no? (of course I COULD be wrong)
Of course, Naruto can't fully utilize his advantages because he's not that smart, but if he were trained specifically to neutralize Sasuke, then Naruto would win.
As for speed, Sasuke depends too much on the sharingan, and the nine-tails chakra can fool the sharingan's ability to predict moves. So on speed they are both pretty equal, I think, one doesn't prevail over the other.
Power, generally Naruto wins, but Sasuke has more penetrating power which leads to more decisive blows.
Lastly, tactics, in which Naruto gets completely owned. It's the truth. Naruto will need training in this if he is to defeat Sasuke.
