I fixed the one guy rank that almost got it right.

Everyone in groups of 5 are pretty comparable. Top row are usually debated as being higher. Others not in the top are solidly in their row of 5.

Top 5 (Top)

ChiPhi/KA/ATO > SAE/SN

Only difference here is SN and SAE have a reputation for being VERY soft. Also their PC's are half usual old row legacies and half random guys you'd expect to go Beta.

Top 10 (upper Mid)

Fiji/PDT > KS/PKA/SX

Fiji and PDT get the rest of the usual top guys the top 5 don't get. Also very soft but also politically different than other groups (ChiPhi is pretty liberal too but less so). KS/PKA/SX these guys are all super solid and throw great events honestly they throw better parties than most of the other groups above them.

Top 15 (mid)

SigEp/BTP/DSP > DTD/PKP

SigEp DSP and Beta all have solid events and guys but are admittedly a mixed bag at this point. DTD and PKP have a great time and both have solid guys too, events are slightly less popular for these 2.

Top 20 (lower mid)

TEP/SP/AEPi > AGR/OX

TEP/SP/AEPi are the best Niche groups at UGA, and they have a great time. All 5 are just geared towards only getting guys in a certain crowd and are mid sized closer groups than above.

Top 25 (bottom but rising/still relevant)

DKE/PKT/TKE > ChiPsi/BYX

The rest of the decent sized niche groups. They're all good here.

Maybe you could group it like this...

ATO/ChiPhi/KA

SAE/SN
Fiji/PDT

KS/PKA/SX
SigEp/BTP/DSP

DTD/PKP
AEPi/SP/TEP

OX/AGR
DKE/TKE/PKT

ChiPsi/BYX
