OK after doing a lot of research, it seems these are some of the best 23-24" IPS panels for gaming:
Asus VG23AH $200
ASUS PA248Q $310
Dell UltraSharp U2312HM $200
EIZO Foris FS2333-BK $430
The Dell has a very matte coating, but is otherwise fine.
The VG23AH has a semi-glossy coating and is pretty great. The 3d polarization coating might show up as vertical lines on solid, light backgrounds to some people.
The EIZO is best-in-class, but expensive. You can get it cheaper if you find a local place that will import it.
Yes, I realize this mostly agrees with the OP. But it didn't have any info about which monitors were good for which purposes.
And obviously, if input lag is your biggest concern (fighting game players) then just get a TN.
