Gotta go with the undead. HL is certainly a brilliant, sadistic killer, but he is confined to the realm of the living and will grow old and die just like everyone else. Sure he can eat a mummy, but would that necessarily kill the Mum? I think not. When all else fails, you gotta go with the cursed undead wrapped up in a tight package. The mummy may be slow, but he is relentless in his pursuits.
