reputations of the top 3 houses?

They're all really good and are pretty similar. They have slightly different reps, though.

DDD: Popular, pretty, classically top tier. Everyone knows of tri delt before even coming to Villanova. The past two years, they have had inconsistent pledge classes, but they are definitely still top three.

KKG: Boujee, rich, pretty. Their last two pledge classes were really strong, so they are in a good position for this year. There are lots of issues with them being cliquey and only bothering with people that are "cool enough". Also, their Instagram is whack.

AXO: Edgy, fun, cool. Definitely more of a laid back vibe. They are known for partying, but truthfully I think it's about equal among the three. Pretty solid pledge class last year, but still probably slightly trailing DDD and KKG in tier.

Above descriptions about axo and kkg are true.tri delt is hard to rank. The popular girls are like axo and kkg but the weird girls are just weird.
