i think that due to their different methods and motivation that they would be equal in power, until Naruto goes Sage mode or RS. lol. I mean Naruto is open to training with ALL of the Konoha 10. which would help him a lot. but remember i did say he would be training with J-Man more and i do believe he is more powerful than anyone Sasuke would be training w/ Kakashi included.
a fully trained J-Man student is more than on par with a student of Kakashi don't you think? But anyway it is called Naruto so Naruto would be the most powerful BUT Sasuke would be 2nd most powerful in Konoha
