the only 5 frats and sororitys that matter

There is no point in making rank lists for ASU greek life because there are only 5 sororities and fraternities that matter and based on preference they could all be considered top tier.

Fraternities:
DKE
Kappa Sig
Delta Sig
Sig Chi
Sig Ep

Sororities:
Alpha Phi
AXO
DZ
Theta
Pi Phi

Fraternities are subject to change (Delta Sig and Sig Chi especially as they are less established as top fraternities), however, these 5 fraternities get along pretty well (except Sig Ep) so I think these 5 will stay where they are as they have been feeding off each other. The top 5 sororities haven't changed in a long time and will probably never change.
