What a fun thread!
I would have liked ZTA based on their colors, symbol, philanthropy, and b/c they are also part of the Farmville Four
.
I have also always liked Pi Beta Phi, because a girl that was one of my friend's roommates in college had transferred to our school, and where she came from she was a Pi Phi, so I got to see the colors and badge of a sorority I was not very familiar with at the time.
I also like Chi Omega, since their colors are really pretty, have a cute mascot, and also since they were founded at University of Arkansas, home of my favorite football team!
