Silent Hill v.s. Resident Evil

[atom36]

Now I grew up playing both of these series on the ps1 ps2, & now ps3, Hell I still have all the games. But I was recently debating with my friend on which series was better during the actually survival horror years (ps1 & ps2 years, silent hill has actually pretty much stayed the same but we were discussing between resident evil 1 - code veronica & silent hill 1 - 3) Now in your opinion which WAS the better SURVIVAL horror series (don't count re 4 or re 5) & why was it better. Now I've LOVE both series but silent hill 1 & 2 have been the only games to actually scare me, but resident evil always seemed realistic to me (I mean the zombie outbreak not the B.O.Ws) & I always had fun playing resident evil because I wasn't scared, but I loved silent hill because it could scare me & the suspense was far better on silent hill then resident evil, plus silent hill's monsters have always been more unique then resident evil. So I honestly can't pick between the two. So which do you like more & why?
