I like both sub and dub, but another anime I feel was dubbed well that I haven't seen mentioned was Hellsing. Both of sub and dub were good and they didn't change how the sub version was worded much. I would watching it souly in japanese... but I unfortunatly know only a couple words here or there and maybe a fraze or two, but not enough for me to follow or carry on a conversation, still working on that one.
