Both are good? There's different types of horror.
Although I don't really like the older horror movies. The effects and acting aren't good enough. Older Scream movies will always be an exception but that's because it's more comedic horror.
I'm not sure if I could ever find Freddy or Pennywise scary anyway. Not that much scares me at this point. I thought the Silent Hill movies had their moments. Heart Eyes is more comedic horror but it's really good. Terrifier series has been okay too.
