I'm not in Europe, but I would be on Team Ghosts any day of the week. I don't like Zombie stuff in general, it's gotten pretty formulaic, and it's just too depressing. Ghost stories have always interested me much more. There's more variety to them, and the stories wind up being much scarier, as ghosts are a much more unbeatable "monster."
Between the two, being a ghost would be a much better existence. Being able to go through walls, scare people, go BOO! once in a while, all great stuff. Zombies are mindless, rotting, shambling, corpses. That would be a lame existence.
