I´m not comparing anything other than my thoughts after the initial first episode. Since I read quite a few posts (although I think most, if not all, of them talked about the manga rather than this first episode) saying it was a slow start. Apart from One Piece and now Soul Eater all of the shonen shows I´ve seen are shows that grew on me until 10-20ish in which they became pretty damn cool with a few climax fights and the usually upgraded animation.
I think Soul Eater has got the best 1st OP too.
