what are the real sorority rankings here?

Top Tier: Alpha Phi, Delta Gamma, Pi Beta Phi. Middle Tier: Chi Omega, Kappa Kappa Gamma, Tri Delta. Bottom Tier: Kappa Gamma and Gamma Phi Beta. This is based for some off popularity, others for achievement but I want to stress that we are all good houses and you should choose the house that you feel at home in. Have a fantastic rush!

In order...
Top: Alpha Phi, DG, Pi Phi
Middle: Chi O, Kappa, Theta
Bottom: Kappa Delta, Tri Delta, Gamma Phi

I Alpha Phi, Chi O, DG
II Pi Phi, Kappa, A Chi O, Theta
III Tri Delta, Kappa Delta, Gamma Phi

Top: DG, A Phi, Pi Phi
Middle: Chi O, Kappa, A Chi O
Bottom: Tri Delt, Kappa Delta, Gamma Phi

You all must be joking. Pi phi is mid tier, chi o is top. theta is bottom.

aphi, dg, chi o
kappa, pi phi, axo
kd, gphi, tri delta, theta

My opinion based off popularity and from what I've seen..

Top Tier:
Delta Gamma, Alpha Phi
Top Middle Tier:
Pi Beta Phi, Chi Omega, Kappa Kappa Gamma
Middle Tier: Alpha Chi Omega, Delta Delta Delta, Kappa Alpha Theta
Bottom Middle Tier: Kappa Delta
Bottom Tier: Gamma Phi Beta

Top:
Phi, DG, XO
Mid:
AXO, Kappa, Pi Phi
Bottom:
Tri Delt, KD, Theta, GPhi

In this order:
phi
dg
xo (i prefer xo to dg, however)
piphi
kappa (pi phi and kappa are basically tied in my mind)
axo (lowest of middle tier)
ddd (improved a lot recently)
kd
g phi and theta tied for last

Everyone tends to rank sororities based off of looks and popularity. So I'll categorize the sororities.....
If you're looking for a sorority ONLY for looks the top houses are:
-Alpha Phi
-Chi Omega
-MAYBE Delta Gamma although the girls' looks have gone downhill
If you're looking for a sorority ONLY for sisterhood the top houses are:
-Gamma Phi Beta
-Theta
-Kappa Kappa Gamma
If you're looking for a sorority ONLY for academics:
-Pi Beta Phi
If you're looking for a sorority ONLY for a variety of girls:
-Alpha Chi Omega
-Gamma Phi Beta
-Theta
-Kappa Delta
If you're looking for a sorority ONLY for partying:
-ALL OF THEM
Seriously....don't think of only one thing when looking for a sorority, they all have their pros and cons and ALL OF THEM have terrible reputations. Go to each house with an open mind and have fun because it only happens once. Don't be the girl who chooses a house based off of what other people say about that house, then hate it once you're actually part of it.

Alpha Phi - known for looks, but also for being stuck up and uninvolved
Delta Gamma - looks and money, fun philanthropy
Chi Omega - looks and not involved
Pi Phi - academics
Kappa Kappa Gamma - sporty and loud, lots of partying.
Alpha Chi Omega - random mix, but really involved on campus and a lot of partying.
Delta Delta Delta - awkward and tries hard but really involved in Greek life and has a fun social life
Kappa Delta - WEIRD! But great sisterhood
Gamma Phi Beta - cant handle liquor well, worse for looks, but GREAT sisterhood
Kappa Alpha Theta - new, awkward, random girls no house wanted but they have a good sisterhood and are really involved trying to make a good reputation.
