pike or sigma chi?

Really you couldn't go wrong with one or the other. Sigma Chi definitely has lower grades, but overall you'll do the same at any fraternity.

They're both national power fraternities, so that's good.

EX has one of the largest houses in the nation, but Pike has an arguably nicer house.

They both take plenty of out of state guys; neither of them are ruled by in-state members.

EX has a lot more on-campus history and has been near the top 3 house plenty of times. Pike is on their way there with consistent pledge classes.

Both have been hit by probation in the past 5 years, but they're clear now.

The similarities are uncanny. Personally, I'd go Pike because I think the guys are little more high quality and the house is marginally closer to campus. Also, good ties with AXO. But that's just my opinion. EX offers a lot as well.
