I say big because then there is more room to move around and run from the zombies, but on small maps you can get cornered easier I think. Also on big maps there is more to explore.

I like either small or medium because you can keep an eye out for the zombies. But the cons of which can be that once they leak in, you're gonna die, probably.
i like medium or big small there is nowhere to explore and you die easily but huge you get killed before you get to explore it all i say the derreise map is big enough
Large would be good for me because, I like to explore the maps get easter eggs etc, Smaller maps would be insanely hard because there wouldn't be much places to run or hide. And huge maps would just be to easy because there would be glitches in the map for one, and second there is way to many places to hide.
