Dubbed anime is fucking stupid, Tiff. But that's up to you and how you like to watch anime. Terrible voice acting or original voice acting.
In all fairness, the original Japanese voice acting is often pretty terrible too.
That said, many Japanese dubs do feature noticeably better acting than their English equivalents. And even when they don't, I just find the Japanese accent to be more pleasant to listen to. There's something really annoying about the American accents used in many anime dubs, especially when over-acted in the way anime so often is.
The only dub I've listened to which I've preferred to the Japanese original would be Steamboy. That was absolutely superb. The acting wasn't amazing (though it rarely is in anime, in either language), but the amount of attention they paid to making sure every character sounded exactly as they ought to really paid off. If only more anime dubbers put that much effort into it, they probably wouldn't be nearly as bad as they often are.
