to sum it up different jutsu then chidori
EDIT: PS Sasuke also has tsukiyomi, in addition to the (as far as i know) unnamed genjutsu cast with normal sharingan that both Itachi and Sasuke used on Orochimaru, it pinned him down with what looks like railroad ties or ice picks. That doesn't even cover the variety or fire jutsu he uses.
Don't get me wrong I'm not saying Naruto only knows Rasengan
