I like subs more, but dubs are cool too. It really depends on the anime; for instance I love the Soul Eater sub (especially the voice of Medusa) and don't like the dub. Where as I love the FMA dub (especially Lust's voice) but not so much the subs.
A big contributor for me is which I heard first. Whichever I heard first is the one I'm more used to and therefore prefer.

Definitely dubbed, but I also like a few anime shows in subbed.

subbed!
fairy tail and hayate the combat butler r the only ones i like in eng dub!

I prefer subbed

I love subbed, but Ian Sinclair and J. Michael Tatum have *amazing* voices. I could listen to them all day. In fact, I have. ;)

Depends on the anime, but mostly dubbed.
