I would say in story terms the manga is miles better than the anime right now. In terms of enjoying the anime Vs manga, if the anime was to be paced like it was in the original Naruto series with the same awesome music, then I would prefer to watch the anime. However since Shippudden is shit and will not be going back to how the anime was I would say start the manga. It takes some time getting used to still images in black and white, and admittidly there are some fight scenes in the manga where I don't know what the hell is going on because of how it is drawn.
