Both are killer pickups for rhythm and lead.
The MM is the tighter, but that doesnt mean to say the pig isnt tight: its is, very much so.
I would go for a ceramic warpig: OUt of the bands you mention I know death and vader very well and the others not at all. You havent said much about cleans, so I assume its not important to you, and the miracle man is a little sharp for bands like vader, great for death. The ceramic pig should get you in between: a very powerfull, very heavy pickup with a tighter bass and sharper treble than A5 but not as sharp as the MM (I wouldnt go for A5 for the sounds in there that I know). Straight up MM would be my second choice, and EQ it accordingly.
Hope that helps.
