the only ranks you need

TOP

Theta Chi
Pike

these orgs are the most relevant and the most preferred by top sororities for parties/events. this is pretty much indisputable tbh.

UPPER MIDDLE

TDX
Chi Phi
Pi Kapp

these orgs are relevant but are a clear step below the top tier. they are less preferred for events with top sororities but still do stuff frequently.

MIDDLE

Chi Psi
Dphi
DKE

these orgs are relevant sometimes, they have OK relations with top sororities but do stuff much less frequently than top/upper middle. in the case of dke they more get used for their house but they are still kinda relevant because of that.

EVERYONE ELSE

really a big drop off after the ones i listed above, plenty of other frats have their day in one way or another but aren’t consistently relevant throughout the year.
