Saw this guys rank in the comments. Tweaked it

KS/ATO/BTP
Fiji/SAE/PKA
SX/TKE/SN

KS and Beta got the best classes, and even if Betas house parties aren't good, their off campus stuff more than makes up for it. ATO is nerdy but clearly the best group of techs nerdy crowd. SAE SX and PKA all need renovations but this is where I feel each is rn. SAE is falling but will always be top 5 or 6 due to history and pull, Pike is not top 3 but is really good still, and SX is really good still too. TKE and SN are both groups with very solid housing and decent guys but TKE are burnouts and SN is still building better srat relations and PC numbers.

PDT/OX/ChiPhi
LXA/PKP/SigEp
DX/AEPi/ChiPsi

The top 3 here are all very solid and have good house parties that are better than some groups above (BTP/SX, maybe Fiji/SN too). PKP and LXA are recovering from suspensions and SigEp has the worst nationals rules to deal with. If they didn't have those rules they would be top 5. DX AEPi and ChiPsi all have at least 1 party a year that a lot of people show out too and AEPi has amazing tailgates. Still not super popular.

KA/SH/GW
DTD/DU/ASP
DSP/PKT

Either super new or just came here too late to compete with other groups here. SH GW and KA admittedly have a decent presence on campus. The others you may see around.
