well, having not tried either, but going from what i've heard from people who've tried/owned both, and my own general understanding of pickup components:
Warpig is alnico V. This makes it sound organic. Better cleans than the MM. More gain (MM is still super heavy, though). Not as tight.
MM: ceramic, so very tight. Not as organic sounding, so not as good cleans (still excellent for ceramic). Excellent lead tone (from what i hear, better lead tone than the warpig). More built for shredding than the warpig.
Both are excellent, basically, from what I hear, they're just slightly different. Again, from the bands you've described, I'd say you want the Miracle Man. All those bands are tight, and use EMG's (well, chimaira do (i think), Matt from trivium does, and BFMV sound like they do), and the MM is closest to this sound in the BK lineup, as far as i know.
