Honest Ranks of Sororities

AXO, XO, KKG, PHI MU, ZTA (no rank in the order)
AGD, ADPI, KD, PI PHI
APHI
DZ, GPHI
AOPI, DG
KAO, SK

Literally when it comes down to it there's good desirable houses who will have stronger academics, sisterhood, social scene, etc. not saying all of them have all these qualities but the ones that have generally been better are: AXO, AGD, ADPI, XO, KKG, KD, PI PHI, PHI MU, ZTA (no rank in the order)
Bottom line with these, someone will want these houses over other ones- just depends on the type of girl. Obvi some houses on this list are better than others, but these are all well seen houses.

APHI is desired to a certain type of girl.

DZ & GPHI are similar to APHI but don't have the same pull.
AOPI, DG are still good houses just not as strong as the houses above. KAT & SK have been working hard and have been getting stronger pc's, but again just not on that same level as others.
