I've dated girls who've done modelling and acting - one of which was was on billboards for Apple and shit like that. She was very pretty and more physically attractive than I am. And yet I would've eventually broken up with her if circumstances hadn't forced the end of the relationship because we were too different in fundamental ways. I've also dated girls less attractive than me because they were great conversationalists and had fantastic senses of humor.
So it just depends, really. Looks matter, but not as much as personality. I mean, have you guys ever been around a really hot girl with a shit personality? It's agonizing. There's a girl like that in my life right now - public relations ESFP chick. Big tits, tight clothes, sex appeal out the wazoo, really outgoing and all that. I think she's attracted to me but I can't stand being around her for more than 10 min. Too much chatter about herself, not particulary bright, has no mystique or intellectual appeal, so....meh. I'll take her nerdy programmer friend who's 40 years old, though.
