I like both.
Anime is good, because you get to see what you wouldn't see in the Manga. In the manga, the attack scenes aren't the best, because you don't see it in action. In the anime, however, you actually see the characters fighting and slashing eachother in action, etc. etc.
Manga, however, is awesome, because, well... I like to read!

(P.S: Can someone move this to (Non)Tamatalk?)
