Michael takes care of buisness, he doesn't shoot people in the eye with a fishing spear from 100 feet away or lightly choke them to death. Michael will take a pitch fork and ram it through your face or pick you up by your head, and slam it into a sharp pointed object sticking out of the wall (sorry, I have no clue what that "sharp pointed object" is in Halloween 6).
Jason will kill each and every person he sees, for the most part. Michael is possessed and has a mission, to kill his family. Jason and his lame music (sorry, had to throw that in) are a sad excuse for killers. His goofy looking, deformed eye and bald head makes me laugh, it really does.
