Well, from what I can tell the Frats that most sororities want to mix with/do homecoming with would be:
1. Fiji
2. Beta
3. Phi Delt
4. Pike/Sigma Chi/ Kappa Sig
But, that is just the most popular among the majority of the girls.
Judging by the type of guy you would want to marry, The best, sweetest, most down to earth, caring guys...no contest... THETA CHI!!!!!
Second would be Farmhouse and Beta.
