I can't help with 90's yet, but do have some coming.
I've been trying to get some consistency (for too long) out of A-Max 105's with no luck, so I've put them away and ordered some Hornady 103, 108 and also some 90gr Sierra TGK.
A2520, CFE and LVR appear to be the most popular, I tried Tac, Varget and A2520 and chose 2520.
27.09gr of 2520 and a 105gr A-Max net me 2528fps, SD 6.4, ES 21 using Fed 205MAR primers.
Oddly regular Fed 205 primers are lower, SD 5.4, ES 15.
That may well be my Triggertech not wacking the MAR primers hard enough (?) that's the only possible reason I can think of, but doesn't necessarily make it so.
