As of this past year pretty universally agreed

Top: Kappa (stereotypical blonde, preppy, pretty sorority girls), Beta (more city/ cool girl, fun, got a very good last pc), Chi O (used to be cool rich girls - now is more fragmented and they didn't rush well last year). Middle: Tri delta (known for being sweet put together girls, often southern/ christian. Mid-low: Delta Zeta (kind of random mix of girls that could have been in other houses - normal girls but not "top" girls), KD (generally known for being a bit earthy, funny and accepting, not your traditional sorority), Bottom: ADpi, below that Theta (didnt have enough girls to keep their charter)
