Naruto was the boy who had nothing but gained everything...Sasuke was the reverse in that he had everything but he turned his back on it all to walk the lonely path of power & revenge... While Naruto has never been a "black-and-white" series in terms of how things turn out or which side wins, i think his happy ending has a duel to the finish with Sasuke losing... ...or ending B which is like his father he gives everything up in a selfless act of sacrifice for the village...
