All the fraternities at U of Mich.- Ann Arbor are equally all good in their own ways. I would say that the ones that stood out the most when i was there were (in no particular order)....

FIJI
Sigma Chi
Beta Theta Pi

These are the ones that always held a spot in like the top 5 thats stood out. Hitting the top 10 would be...

Theta Chi
PIKE
Phi Delt
ADPhi
TKE

For NPHC's... Kappa Alpha Psi and Alpha Phi Alpha
