Dubbed, unless the dub is exceptionally bad. Dubbed also allows me to have the show going, not be watching, yet still keep track of whats going on, because tones of voice only go so far. Also, Japanese have weird onomatopeic sounds, like "EHHHHHHHH" and ""Ah-ha" (with the head falling to the shoulder), these grate on me.
Honestly, I believe alot of people go for subs in an attempt to hide their powerlevels from their friends and families.
