User blog comment:SlenderVSJeff/Slenderman or Jeff The Killer?/@comment-5456574-20120829154553/@comment-5358846-20120829230751

I don't know, Jeff seems pretty interesting to me. The original "Jeff the Killer" pasta isn't very good, but that image and the newer "Jeff is Back" Creepypasta and video are very thought-provoking, in my opinion. I don't know if this only me or what, but Slenderman doesn't really creep me out that much (he does scare the crap out of my friend, though).

If they existed, I'd rather have Jeff come after me than Slenderman. Jeff is (supposedly) a very dangerous, very strong, very intelligent, highly unstable serial killer, but he's only human. He can be killed if you are fast or strong enough. On the other hand, Slenderman is a truly paranormal creature. You can't kill him; the best you can do is repel him for a short time.

tl;dr: Jeff is creepier, but Slendy is more dangerous, if the two were real.
