If I had been a boy at my undergrad campus, I would have been a Sig Ep legacy, so I would have strongly considered them, esp. since I'm daddy's little girl (meaning, if I was a guy, I would have wanted to join my father's fraternity).
Other than Sig Ep, my top choices would have been Sigma Chi, Lambda Chi, Pike or Pi Kapp. Although, the Sigma Chi's didn't have a house and just had land, so that probably would have been a factor in my decision.

But they were an awesome group of guys w/ a strong brotherhood.
Since I was a Pike little sister, I guess I would have been a Pike. But I did hang out w/ the Lambda Chis and the Pi Kapps a lot.
I probably
should say Sigma Nu, since they are my sorority's unofficial brother fraternity...
