Nightfall: I actually voted for BOII zombies being the best for the very reason that it returns to the base survival element... in four maps, at least. Town, Farm, Bus Stop (admittedly I never play that one), and Nuketown Zombies. Those have no objectives outside of opening a couple of doors and buying the perks and PaP.
