If the dub is good I prefer the dub, just because I can identify with it easier. I can watch in subs if there's no other option though.
Also, and this may just be me, some Japanese voices really grate on my nerves. DBZ's Goku for example, he sounds like he's 10. There's others, but it just doesn't work for me. It's the same any time they try and do an accent in Japanese, it just doesn't sound right.
Also I feel that this should be posted, as a plus for subs.
edit: I ended up watching the first 40 episodes of FMA Brotherhood dubbed in english and then watch the rest in subs. Since i'd been used to the english voices all through the first FMA anime and the first 40 episodes of Brotherhood I couldn't see the characters sounding any different. I never got used to the new voices and sometimes when a character was talking off screen i'd get lost.
