I generally dislike dub, theres only two dubs that I can accept at all and that is the Full Metal Alchemist and The Melaconholy of Haruhi Suzumiya.
Honestly I tried a few others like the Shana dub and the Fate Stay Night dub but just couldn't bear listening to the dub. Same with Cardkaptor Sakura, uh... they just sounded too old for their age.
