Hmm. I like Clancy simply because she plays stuff I haven't heard. Kines, Berzon, and Sanchez always seem to play stuff I'm already familiar with. Not necessarily a bad thing; someone has to play Time Out, but I've heard it enough. Buxton I consider overrated, though even overrated he's pretty damned good, and Berman I like, for the same reasons you mention. Conte, as you say, is okay, though a little goes a long way with me.
However, in all honesty, I have to admit that I haven't listened to KCSM all that much since I left the Bay Area. Radio has become a "forgotten media" for me, I'm afraid.
