overall best sorority?

DG- There are a lot of really pretty girls and they all seem to be pretty fun and go out a lot but don't have a very good retention rate surprisingly. So many different types of girls in the dg though. theres like 10 different small friend groups in every pledge class. They have the best chapter house and its closest to campus.
Pi Phi- They have a lot of really pretty girls but are known as more laid back and I think they've had top GPA for 5 or maybe more quarters straight, they don't show up to all of the stuff that goes on in greek life though.
Aphi- There are a lot of different types of girls in Aphi but with the exception of a few random ones ive seen theyre all really hot. best retention rate also. Not a popular sorority from the standpoint of girls in other sororities but most guys love them.
