The MAIN reason I believe Naruto would beat Sasuke in a fight.

[iAmSoulNuke]

According to kishimoto sasuke = naruto and since he writes the story im going with that.

Sasuke has perfect chakra efdiciency unlike naruto. Narutos big attacks like tbbfrs take up a ton off chakra while sasukes big attacks namely ps slash takes up next to nothing but with the same effect.

Naruto easily has ATLEAST equal chakra control compared to sasuke, but saying his ps slash would have the same effect as a TBBRS is quite ridiculous :|

Ive never taken you as big trolling type so i give you a serious response.

He would outlast him. He's got too much energy, strength and chakra, plain and simple.

Too many forms. Base, Sage, KCM, BM, BSM, Prime Base, then BSRM.
Sasuke has base, EMS, then Rinnegan. Each of those forms consume chakra, and it's not like he gets a heal or boost with every escalation.

On top of that, every time he (Naruto) escalates to the next form he gets a heal. Pretty sure his chakra gets refilled too.

I think that's too much for Sasuke. I don't mean to take away any credit for him, because that's something he can't help. Yeah he has a lot of chakra, that's undeniable, but that's not one of his dominating qualities as an Uchiha. He has a strong body, having more chakra by default is Narutos'.

So yeah... just wanted to put that out there.

Plus Naruto is the good guy xD

Good point.

As manga stated they are equal, so in terms to level the play field Sasuke may attain the 'Preta Path' powers due to the rinnegan.

it's legit , but not if the fight settles b4 they have to start worrying about lack of chakra
