Aliens. Zombie is just a slow-ass death. Most people will obviously flop and turn into one. Android... no thanks. Not here for Terminator/Borg mess. Nuclear War and Disease seems like a straight ticket to death so they're ok... At least with Aliens there's at least some intelligent and we might get involved in an intergalactic conflict and form alliances to stop and we'd ultimately advance, at least technologically.
I would build a cool survival team.
