Subbed! The original Japanese sounds so much better, and just more natural! I don't like it when they change things in anime like names, objects, places etc.
Well, I suppose they are trying to Americanize it a bit, just so the Americans can be familiar with it or something like that.
Dubbed anime is really bad. Sometimes its quite good, personally the only anime dub I liked was Princess Mononoke (Mononoke-Hime Mononoke王女)
That was the only anime dub I liked, the others were horrible. Japanese with subs for me.
