Lots of campuses have lots of different orgs. I will say this: At Platteville, Sigma Phi Epsilon was far and away my favorite fraternity. I was a little biased, after all.
They did not, however, throw the best parties. That honor is a toss-up between most of the other houses on campus, many of whom are on probation for throwing such great parties.
At Marquette I do not have anything nice to say so I will not say anything at all about the majority of the groups. The men of Triangle are very nice.
