I couldn't tell you what any of those people (besides Laura Bailey) have been in (as far as anime) other than Bleach and I doubt most people outside of the most hardcore otaku(s) could either. That's not a snarky jab or anything, I'm being sincere.
When I think of a "who's who" list I look at it as the best or most iconic voice actors in the industry, not a bunch a regulars. Maybe that's not the norm, but that's how I personally look at it.
Who the fuck is iconic in anime aside from the regulars?
Vic Mignogna is probably the most popular/famous anime VA in America other than Steve Blum (he's Edward Elric, among other things). Beau Billingslea is Jet from Cowboy Bebop. Wendee Lee is Faye from Cowboy Bebop. Spike Spencer is Shinji from Evangelion. Wally Wingert is all over the place, both in and out of anime. Outside of anime he played the Riddler in the Batman Arkham games and like half the supporting cast of Family Guy. Troy Baker is in EVERY game, most notably recently as Joel in The Last of Us. And so on.
