For me it can be either, it depends on what I notice first to be honest. Obviously, just because someone is good looking, doesn't mean I'm going to approach her and ask to get to know her... But like, if I meet them the first time, and they are funny, nice, have a personality that I like, that will be what draws me, if they are good looking, and not just like physically, but fashion sense, if they seem confident and stuff, then that can draw me in as well.
It's the whole package really, but it can be either which catches my attention ultimately...
