most accurate rankings

Okay, I agree with the post below me but the only thing I would change is placing Sigma Chi in top tier. Anyone who disagrees is probably in a low-ranking fraternity or sorority. If you ask anyone on campus, these are the most accurate rankings.

In no order....

Top Tier:
Fraternities: Sigma Chi, Sigma Alpha Epsilon
Sororities: Kappa Kappa Gamma, Phi Sigma Sigma

Middle Tier:
Fraternities: Sigma Pi
Sororities: Alpha Sigma Alpha, Chi Omega

Bottom Tier:
Fraternities: Tau Kappa Epsilon, Delta Sigma Phi
Sororities: Alpha Delta Pi, Alpha Chi Omega
