Painkiller will be too bright.
I haven`t used either of them, but if you like Cold Sweat and have alder/maple guitar and looking for metal pickup, it`s definitely Miracle Man. Hands down.
you might also consider CBomb, I have one in all mahogany Dean Cadillac (totally opposite sound wise to your guitar), but once I play few songs in drop C sharp, it gets muddy, looses definition a bit and cannot keep up with lower tunings in my opinion (or to my taste...)
I dont know how CBomb will behave in brighter guitars, but Miracle Man I think is your pickup without the shadow of the doubt.
