Horror films, which type do you find scariest?  

Definitely the Japanese horror types, because although you might not be that scared while watching it, the movies tend to stay with you and are still scary hours after you've finished watching them.
The gory ones, well, they don't scare me at all, yeah, they can be jumpy because of the loud music and random startles but that's not really horror, you're just shocked when you see those scenes and the experience lasts only until you're inside the theater.
You're right, the other kind does have a tendency to haunt you and make you think, long after the movie is finished, plus they're more realistic, in terms of true stories and ghost stories that we've heard our whole life, and that really hits home, but a zombie is hardly real and you know that's definitely no chance of actual existence with those.

I am a big fan of the horror genre! and enjoy both types of it! the American slasher movies like Texas Chainsaw Massacre and Zombie flicks like Dawn of the Dead.

But one thing that gives American Movies the edge over their Asian counterparts is that American movies are fast paced whereas movies like Grudge are a bit slow to begin with! but that doesnt mean they are not scary!! in short i love both types!

I'm also a horror fan and i have to say that japanese horrors are way scarier! Although i've seen some good american ones like The Blair Witch Project 1 that haunt me long after i finished seeing that movie.
I was also impressed by a thai movie that i've seen some time ago - highly recommendable for asian style lovers - The Shutter.

Asian horrror films are far more scary,

Evil little girls are soo scary

For me it's definitely Japanese movies. There's a bit in the second Ringu movie that still freaks me out just thinking about it even though the rest of the movie isn't that good. A movie such as Dark Water was also scary because it deals with a ghost and the atmosphere is very oppressing.

None are really scary if you understand the nature of evil and know that you are watching a movie. We don't get too concerned about anything we watch unless it is the House of 1000 corpses. That got pretty intense and it appears to have happened for real at some point. yuck. Grudge was simple and there was a need for the spirit. Really like the Ring, poor little girl. Zombies are intense yet with the right tools manageable. We do like a movie to leave some things to the imagination since it is better normally than anything that can be shown on the screen.

I really dont prefer to watch horror movies.... even if i watch one i dont get scared... touchwood...!! But Zombies are an exception... i get scared only because of the Special effects and the Surround sound...!! Otherwise i could even walk a lonely road with being scared ..!!

Well.. japan horor is more scary -hiiii-
Mandarin horor, korean also scary...
Now western movie also try to do like Asian way... but I think there are still more daylight in western horror movie... in Asian movie, I'm stuck with the darkness all the time

Oh the Japanese ones are definitely the ones that scare me most. The Japanese original of "The Ring" was much scarier than the Hollywood version and as for "The Grudge" .... I was freaked out by that movie for days!! I think they're more effective at scaring us because they're not so "obvious". They're more atmospheric than most of the American ones which tend to be more gruesome.

japan films. american films are ok, but who doesnt love getting scared to hell by a small girl comming out of a tv?
