Once again I am making a biased, ignorant choice because I have seen one but not the other. I love Soul Eater! I really enjoy the art style which is kind of horror + modern art + a little avant-garde. It's the right blend of action and humor. The characters are super quirky and loveable. My favorite character is Black Star--YA-HOO! He's all brawn and no brain, but something about the way he just rushes into things and always wants to be #1 makes me love him. Also, he's probably my fave due to the fact he makes me laugh the most. The story for Soul Eater is fantastic and unpredictable; I really want to get around reading the manga.
