Naruto and Sasuke are most likely equal in power and strength. If one was more powerful than the other there would be no point in having an epic battle which everyone has always wanted from the get go. So Sasuke's power most likely matches Naruto's. But Naruto will win because of sheer will.

His will is greater than Sasuke's because not only does he want to save the world, the tail beasts but also wants to save Sasuke once and for all and to finally end the conflict.
