What I find is the Nailbomb is smoother and more balanced and the MM has its output in its select frequencies.
I find loud ceramics are typically good for pinching, soloing, pinching, riffs on the low E string but not downtuned, pinching, cutting over the mix while soloing, and pinching where the Nailbombs can do all that and clean up too from what I've heard.
I cannot correctly answer this without knowing exactly what you are looking for in terms of thick, but if you want lows that will make the floor shake first, the MM gets it.
