KD considered lower/mid

I don't think they are. Most people have ranks looking something like this...

Clear top 2

ZTA then ADPi are the most desired seats for girls and both are ATO KS PDT ASP and Beta favorites by far. And since those are the best frats with houses it makes it obvious. ZTA is significantly more popular and less strict than ADPi but there is a much bigger gap after ADPi.

Other great sororities, put them in any order In no order

XO DDD KKG KD Aphi AXO

All 6 of these sororities are very desired by girls and also very popular with boys. Every sorority here except maybe KKG has a top 5 fraternity wild on them. XO (BTP & KS), DDD (ATO), KKG (BTP), APhi (PDT & KS), AXO (PDT & ASP), KD (ASP) but usually hang with good mid groups like PKA, SN, PSK, Fiji, ChiPhi, SAE etc.

The top 8 here other than the top 2 can go in whatever order you want. No one thinks KD isn't good here. They're at parties and tailgates for every relevant frat here.
