The question was simple: purely from a "it would be easier to survive" standpoint, would you rather be stuck in an on-setting Xenomorph (Aliens) infestation or an on-setting Zombie apocalypse?
I said it'd be easier to survive the Zombies, my friend believes it would be easier to survive the Xenos.
How about you, my fellow Escapists? Which horde do you believe would be easier to survive?
Edit: Since it seems the Xenos are winning out as "deadliest by far", I think I should go ahead and make a stipulation that should hopefully balance things out for the rotting ones.
As for the "class" of zombie, rather than thinking of the classic, shambling bunch of morons from the old-school zombie class, assume that the zombies in question are the "new-age zombies". That is, the super-psycho sprinting-at-full-speed zombies as seen in the remake of Dawn of the Dead and "technically" 28 Days Later, though I'd argue those are more mutant than zombie in that movie.
