There really isn't negative to say about those houses. They're all great and you'd be lucky to end up in any one of them.

Pi Phis are snobby and conceited. Chi Omegas are boring and only care about grades. Thetas are hippies who only care about grades. GPhis and Kappas are rich and snobby.

I assure you that you will find wealthy people, some conceited, some hippies and a few study hounds in each of these houses. You'll also find women from average income families, preppy girls, church-goers, partiers and one or two odd ones in each house. That's okay. Each house is a mixture of a variety of women, each with her own strengths and weaknesses. You will join and probably not connect with every single member of your sorority--no worries. It's not that you made the wrong decision. You will find your own group within the house, and they will be friends for a lifetime. Go and have fun in rush. Don't stress.
