Comparing Bleach to Naruto, Fairy Tail, Reborn, Rave Master, Yaoi Exorcist, Pokemon, Dragonball is fine but not One Piece. One Piece is in another dimension.
Don't read Fairy Tail though, it's the 2nd worst series in the world (the worst is Freezing).
And yep, Yoruichi is great, as is Halibel. Overall character design in Bleach is great, although it's a shame most of them lack any personality. Kishi does cute better though.
