ill say face because I won't stand looking at someone who has a hot body but unattractive face. besides, the body can always be changed or improved easier then the face =P. Oh yeah, I just cheated, I feel quite proud =)
For a guy, I'd go for a nice face over a "hot" body. Hot is a subjective term, anyway. What I find attractive in a man's body, someone else might not, and vice versa. I also think that for myself personally, I have a nicer face as compared to the rest of my body.
Definitely face, not even a question! (Well this is a very good question.) A cute face is much more fun to look at and plus who would want to wake up to someone with an unattractive/average face everyday? You look at a persons face more unless you're some type of pervert and the body can always be changed. I don't really care about body I just see it as a bonus really...
Face...I mean it's not like you can do anything about it.
