hmm chambers ..you say don't think Sasuke could beat Kabuto, don't think Sasuke could be Neji, but Sasuke could beat Naruto, yet, Naruto beat Kabuto, Naruto beat Neji, also Sasuke couldn't beat Gaara, Naruto beat Gaara

Well, I would say Naruto among other things, he's the main character, he has kyuubi (more or massive power, healing), he has 2 sannin/kage level jutsu, hmm and Naruto just seems to pull through in the end. Also if it was Rasengan vs Chidori, looks like Chidori takes more time to charge than Rasengan

Also generally if it's Naruto he's fighting to protect,/prove himself/try to be Hokage, while Sasuke''s comes from his passion for revenge which means Narutos drive would be stronger than Sasuke's also as well as the fact that Naruto changes people. He has the effect of making them realize things or just to change them (which you can say happened with Zabuza, Neji, Gaara) Sasuke is a top cadidate for one who needs change so there is another reason Naruto would probably win.
