Even stealth killers have trouble surprising survivors at higher skill levels. Wraith has his telltale breathing and cloak shimmer, Myers also has breathing and is tall. If youre playing him without Scratched Mirror you will be leaving T1 anyways and he gains a terror radius outside of that. Pigs crouch is slow. Ghostface has a reveal mechanic that lets you know if youre looking at him while he is stealthed. Onryo has a lullaby you can hear even when she is stealthed, and she still kinda flickers in and out.

Oh, and there is Spine Chill, which tells survivors you are looking at them even if you are Undetectable (which can be achieved by other means outside of killer powers as well).
