Depends on what your taste is, but I would say one of the best horror experiences you can get is Alien: Isolation. Even at nearly a decade old, it's one of the most terrifying games I've ever played and I don't scare easily. The Alien learns from your patterns and movements so you're never safe. There's a palpade dread that runs through the entire game. The story is pretty great too and there's some great easter eggs and callbacks to the series as a whole.
Other recommendations would be the Resident Evil 2 remake, The Evil Within, Control, and The Dark Pictures Anthology series.
I'm a huge horror nerd so I'll try anything once and usually find something to enjoy in all horror titles. As comes with any recommendations, your mileage may vary.
