Sasuke gets my vote, Naruto is arrogant a somewhat annoying but still really cool with his kage-bunshin (shadow clone) and Rasengan, Kakashi got most of his abilities and skills for the implanted Sharingan eye except for his Chidori which is awesome, and Sasuke is blinded with vengence every now and then but is very strategic, I think he has the potential to go the furthest, him Naruto and Rock Lee.
