Not a maker but as a user I like whatever the maker specializes in, I've used aebl, r2, zdp, vg10, elmax, s90v, ginsanko, vg5, hap40, carpenter steel and probably other stainless steels I've long since forgotten, generally I think there is a certain level of skill in learning the kinks of each steels preferred heat treatment that takes time(experience) to nail down(kindof like cooking a piece of meat), I've had aebl from HHH, Kikuchi, Dalman, Butch Harner and Devin Thomas, they all feel different mainly on the stones, most makers I have talked to really like aebl, it's relatively easy to work with and most have a plethora of experience with it, which means they get good at it, but in my experience I would want to talk to the maker in question if your buying a knife from them, if it's a Japanese blade I would probably just ask on the forum for feedback on item xyz and more than likely people will chime in.
