So I feel like I'm the only one being honest here, I was genuinely surprised to read everyone's responses haha.
I was originally going to say both, but when I think about it, I'd never consider going out with an ugly guy who was really nice, and while I also wouldn't if he was good looking but an *******/boring/just not interested in what I was interested in, I'd be more willing to make allowances for criteria that is normally important to me.
EDIT: ugly to me is probably overweight and doesn't look after appearance, or, uncharismatic AND bad dress sense etc. If he's probably average or slightly below average, I can handle that, if his personality is better.
