apples to organges

-Pi Phi/AXO/TriDelta
-Theta/ADPi

This tends to be the "general" consensus allowing certain chapters to move up or down. There's no way to do a precise overall rank when one may have looks yet their personalities suck. You also shouldn't try to rank the sororities when they each have such mixed characteristics. Pi phi/AXO/TriDelta have some of the prettiest girls, where as ADPi/Theta are known for strong sisterhood. Thetas are known to be smart where as TriDelta is the strongest with philanthropy. AXO's are said to be chill and ADPis are said to be friendly and Pi Phi is always said to be labeled as cliquey.

Best advice: don't worry about the previous labels, the chapters have really been changing and growing within the last 5 or so years so focus on making sure you're being yourself and finding a place where you connect with the girls. Everyone in a chapter isn't a clone of the other, each girl is different. Greek life makes up 8% or so, it's not a make it or break it kind of deal.
