Zombies, mostly because they don't really sleep, can be out at all times and well, the 'super' variety that has most of it's humanity/intellegence intact is definitely preferable than the 'half-vampire'~
I think right now in media, zombies haven't exactly had their time to shine as an individual rather than a mindless horde, but I don't feel that it's too far away when their supernatural abilities will be appealing to the masses~
