which one is better

Obviously DPHIE all the way.
The rule NYU greek life.
But if you are looking for no hazing and actually sisterhood, neither.

They're similar with involvement, popularity. You'd see them at the same events, the same places out. If you had to find a point of distinction, DPHiE is probably a bit more spirited and like a typical sorority, and AEPhi is probably a bit more chill. They both have a strong sisterhood – despite all the negative commenters. They will both only be allowed to take small pledge classes this semester, so everyone should them BOTH (and of course the other organizations in other discussions) because no one is going to be a shoo-in this spring. If you're curious, go out to recruitment and meet them!
