Haven't seen enough films on the list to state with certainty which I consider the best. Definitely saw Shock Waves, Outpost, and Dead Snow. Night of the Zombies and Zombie Lake ring a few bells, but I can't say for certain I've seen them.
Of that small list, Shock Waves hands down takes it. Not that the movie is all that great, but it has a solidly creepy atmosphere, an oddball premise, and Peter Cushing. With that last item being enough to get me to watch just about anything.
