Personally, I love horror comedy. I find a good one endlessly rewatchable. Cabin in the Woods, Return of the Living Dead, Tucker & Dale, Scream, frigging Killer Klowns from Outer Space! Definitely my favorite.
Otherwise I’m really into paranormal & zombie horror. I think that would make up my top three. Fast > slow zombies.
Kind of a toss up, but zombie is up there, along with eldritch/lovecraftian. After that, it’s old school slasher, which is often comedy after the first two or three in a given series lol.
