its hard to say, what i keep thinkin about is how someone can break through that susanoo. sasuke even said its stronger than gaara's ultimate defence

i think their even. always will b. yin and yang

naruto will b always b stronger then sasuke because sucks

Yeah i agree with Naruto_757 and hofstrom85 it is and probably will always be a TIE! Sasuke and Naruto will never even out.ALWAYS AND FOREVER A TIE!

hofstrom85 hit the nail on the head I think. Naruto has Sasuke beat from a power and stamina standpoint, but Sasuke has the eternal Mangekyo (due to Itachi's eyes), Susano'o, and most importanly - brains. (In regards to mesy's comment - yes, Susano'o is a better defense than Gaara's sand, but it also drains a lot of chakra, so getting past Susano'o is just a matter of waiting it out.)

Naruto is far more stronger than Sasuke..xD
