difference between theta, kappa, tridelt?

These are my top 3 right now the vibe I’ve gotten is
PLEASE COMMENT BELOW on other pros/cons for the top three stats:

Theta— blonde, sporty, super sweet, made me laugh but I’m a shy kinda way
Cons:
one negative was that they only have one person of color in the last PC which is really problematic and makes me feel like they’re are I’ll get out. Is theta generally more diverse?

Kappa- SO NICE and chill, all down to earth and a sick house, we’ll put together and rlly rlly funny, soo much diversity, also rlly honesty and made me LAUGH a lot I loved them
Cons:
do you have to be rich? Am I going to be pretending to be someone else? They all seemed SUPER wealthy

TriDelt- literally SO COOL not the typical sorority, didn’t even cover the basics major, hometown, etc. just had the greatest convos literally ever all down to earth and rlllly edgy and honest. Most genuine girls ever
Con:
They all seem so different and angsty. Am I different and angsty enough? I loved them

Let me know on other things to think about with these three.
