Top Tier Fraternities?

[andymiller]

I'm going to college next year, and want to rush. I've been looking at sites like Greek Rank to find which fraternities are considered top tier, but it seems like in each fraternity review there are people saying that that fraternity has weirdos and is bottom tier. In almost every one. It's not just at this school, but as other ones as well. I live in a State College town, which has a few fraternities. I've been to a few fraternity parties, and probably the top tier fraternity here is Pike. Pike seems pretty cool to me, but after reading a lot online it seems that many people hate Pike. Almost one of the most hated ones I've seen, with a lot of people saying they aren't top tier at any school, or at least shouldn't be. So I guess what I'm asking is how are you suppose to determine which fraternity is top tier at a school? What kinds of things should I look for in person, and where might I look online? Also, why do so many people hate Pi Kappa Alpha? And, is there a fraternity that is typically top tier all around?
