Press X to Jason.
While Michael may be the prototype of movie slashers, Jason is god-modded slasher tier.
Jason has had at least two video games based on his hijinks. Michael has none.
Jason has killed Crispin Glover, the one girl from Destiny's Child, and his Mom killed Kevin Bacon. Michael was roundhouse kicked by Busta Rhymes. Granted, Jason was "killed" in part 4 by Corey Feldman, but Feldman has innate Wacko Jacko powers.
Jason makes mass murder into an art form, using anything from his trademark machete to harpoon guns to sleeping bags. Michael has used various killing methods, but his are rather pedestrian in comparison.
Jason went to space, has taken Manhattan, and also fought a dream demon. Michael fought the lady from the yogurt commercials and tried to rape his cousin.
Jason knows how to accessorize, sporting a slightly different look in each film. Michael is forever stuck in a boiler suit and a Willam Shatner mask.
Jason has a song written about him by Alice Cooper. Michael does not.
Jason has not had the indignation of being in a Rob Zombie movie remake. Michael has. Twice.
Only thing Michael has above Jason is John Carpenter's bitching theme song.
