SH2 is my all-time favorite because I am a huge dork.
I am of the opinion that survival-horror games should actually emphasize, you know, survival and horror. The atmosphere is really important for establishing that, and relying only on jump-scares doesn't really measure up. If you get immersed in the environment, it's much more effective at freaking you out. And, I find protagonists who aren't experienced fighters more compelling in this context, since it makes the ordeal they're going through more harrowing. If the character is mowing down hordes of monsters coolly, a) I don't particularly identify with that and b) it takes away from both the survival (you're well-equipped to survive, not struggling) and horror (your character isn't actually afraid so why should you be?) elements.
Don't get me wrong, I like a good shoot-'em-up. But I don't feel like it fits this genre well.
