sororities?

The rankings on the other page seem like kind of an inaccurate mess. What is each sorority ACTUALLY like? Which are the most sought-after? Who is the most down-to-earth? Give any important info! And don't tell me "go through rounds and then you'll figure out where you belong, this website is stupid, blah blah blah" because yes, I will go into recruitment with an open mind-- I'm just curious about peoples' opinions and very excited to rush!
