The Studios one will always be my favorite. Most of my built Lego collection is in the old grays so it's nice to have a Mummy that doesn't stick out in detail or part color among them when I take photos.
I think the dude from monster fighters'll always be my fav cuz the set he was in with the skeleton horse was one of my first as a kid, so I remember it fondly. Wild how many awsome mummy figs there are though, the lady one from the cmf was cool, her doubled sided head almost feels like a deliberate reference to the pharaoh's quest guy
