Well, I watched the anime before I read the manga. I like both. But, honestly I think I like the manga version a lot more. The anime was kind of short, too. Didn't have all the characters that the manga did, and they couldn't cram everything from the manga into it. So, I think that's why they made a different ending to it. I personally would have preferred a 2nd season instead of what seemed to be a rushed ending. I didn't like the Japanese voice actors, but liked the English dubs a lot more, which is pretty rare for me. The English dubbed seemed to be the closest to what they characters might have sounded like. The manga, if I remember correctly, was a lot more complex and drew me even more in. But, with a lot of these, I try to look at them separately. Sometimes it's rather interesting to see a different interpretation of the same plot/series in a different medium. It is after all, an adaptation. They can do things that the other medium couldn't entirely capture.
