People saying Sasuke are generally fooled by the fact that he has a unique fighting style. I.e. He's very acrobatic in his taijutsu, and gives off on "awesome" kinda aura when fighting or executing a jutsu. This does not mean that he is a better shinobi, it simply means that his fighting style is easier on the eye. In the manga, it's all about efficiency, and Naruto is far more efficient with his moves. As of the current Manga, Naruto > Sasuke in every aspect except for Genjutsu and if you cannot see this then you haven't been paying attention to the manga at all.
However I cannot deny that up until Naruto attained Sage Mode, Sasuke was leading the way.
