I prefer manga over anime.
I'm more manga, than anime, person in general, that may affect my decicion too.
Anime has mainly two things I like about it:
1) those mostly awesome BGMs.
2) Fai in the intro (what? I love how he moves in it when fightin' >D It's so againts all anatomy, I think, but still so cool, lol. )
But still, I gotta see rest of the episodes some day (I have currently 17).
