Everything involving voices, excluding some bad-ass Kung Fu movies but including hentai videos, anime, music, etc., I prefer dubs over subs. Why? I'm a lazy American dude; I dislike not understanding a person's speech, I do not want to read through a whole show to understand what is going on, and I do not plan on learning any other languages any time soon. But, if I had to choose subs or not understanding a movie at all, I'd definitely choose subs.
