honest opinion

PIKE prides themselves on being try-hards and douchebags. But really, they think its a positive aspect about their fraternity... lol. Delt is about to be off campus for awhile. Theta Chi... for sure is not one of the "three fraternities that matter" at KSU. Honestly from what I've seen Theta Chi is a rag tag group of guys, just kind of thrown back together because they needed to come back on campus.
Kappa Sig has a few weird kids, but that is also because they merged with the SPSU Kappa Sig chapter. KA, has some cool guys that I've met, but they also have some guys that should have been dropped or not received bids. They also aren't on campus EVER.

Delts are gone hunny! And Pike was is only Top 3 now because they bid everything with a pulse. As for Theta Chach... Theyre just living in the passed rather than trying to rebuild what they had. Pi Kapp's are pretty cool party hard have decent numbers good history here and stay pretty chill so leaving them out and saying they aren't relevant is just being oblivious. As for Kappa Sig, as much as I hate them, they are the best here. The only fraternity that competes with them being popular with the ladies is pike and that's only because they have like 160 guys now (only been here 5 years and already their blanket bidding of everyone who can't get bids anywhere else is making them massive.) And the only fraternity that parties as often is Pi Kapp from what I've heard they rage pretty hard. As for relevancy everyone heard about Kappa Sig's tailgates, their 80's social, their dirty Christmas social, their Pig Jig, their homecoming party and are the only fraternity who did a concert in the fall.
Pi Kapp has risky buisness, their tech excursion, war of the roses and Pie a Pi Kapp as well as countless community service events.
Pike has had their semi formal, a few manor parties which haven't had the cops called, some solid socials as well as philanthropy events.
Easily the 3 most relevant. OX has only ever had desperado week from what I've heard. DX and SAE are hanging on to their little holloween party and KA is still hoping their name will magically force them into top.
