One isn't better than the other. It's all a matter of prefence and opinion. Both myths have under gone drastic changes since their birth. I prefer vampires because I love the myth over the werewolf. For me, the monster that willing accepts evil (depending on the lore you're reading) blends in, gains your trust only to kill you scares me the most. I like werewolves, but only if they are governed by the moon. The moment I find out they can turn at will I lose interest quick. The beast is a curse, not a tool. In video games it's cool, but in books and movies, I don't like it. That's just me. To each their own.
In Skyrim, I feel werewolves have the upper hand. At least until Dawnguard comes out that is.
