Should I join a sorority?

So I'm debating if I should rush, people tell me not to believe the stereotype and that all the girls will be btches and full of drama but I'm not sure if I should. I'm a very chill girl, I surf, play guitar, hang out at indie concerts, go to a few raves, I party quite a bit though, I have a high tolerance for alcohol and yeah I have done some drugs before. I consider myself good looking and I dress kinda hipster/rockerish. I've met 2 girls from delta gamma and they seemed nice and some girls in pi phi said I would be picked basically because of my looks. Is that what they do, pick you based on looks, that is pretty shallow? and im a very drama free person, I chill with guys mostly because they are laid back, but I realize I need some cool female friends for balance purposes, there is some things I just cant talk about with my boys.What do you think I should do, are the stereotypes true or are the girls in the big panhellenic ones that are okay?
