what are the real sorority rankings here?

Yes I would agree. All are really good but based on how others view each sorority and the ones most people want to be in I would say

Chio
Adpi
Zta
Phimu
DDD
aopi

Based on the past few years it’s definitely

Chio
Adpi
Zta
Phi mu
Tri delta
Aopi

Each is so unique and good though!! Chio is usually the girls who do their own thing and what most pnms like during rush. They are super chill and well liked. Adpi is also really good and have talented girls in there. They are more of the picture perfect girls who are stricter but not in a bad way. Very well respected across campus. Zta as most people know are the partiers but then again every sorority has some of that in it. Phi my is the sweet and more introverted girls. All super kind and lovable and have a great sisterhood. Tri delt is new but they are getting better. Have girls of all personality and wide among campus. Aopii can sometimes be seen in a negative view but they are all nice and anyone that gets a bid from them is still cool. They are less known on campus but sweet sweet sweet

There's something positive that you can find in each sorority!

Phi Mus are genuinely sweet girls all around
Zetas are mostly extroverts and are always open to meeting people
AOPis are the girls who are the most diverse in personality
Chi O's are the usually the granola type girls but are also usually laid back
ADPis are super sweet and are always willing to help each other

Where ever you end up, you will find your people, even if it takes some time
My advice: Don't drop and embrace whatever you get with an open mind
