Plague. If it's a post apocalypse, that means you've survived the plague, and are probably immune. It's pretty much plain sailing from then on.
Though, "live" is a bit of a misnomer when it comes to zombies, I mean, I could be a zombie, yeah. I'd probably enjoy it actually. Sure, the hours are tough, and the pay isn't great, but you're your own boss. How many other harbingers of the doomsday can claim that?
Nuclear Apocalypse... not really that much fun unless you have a Geiger counter. Unfortunately, I don't have a Geiger counter. I don't think most people have Geiger counters either. Radiation is completely invisible, and kills you in a very slow and painful manner. For every super mutant or ghoul there'd be over a million people who just get tumours. Oh, and then there's the issue with disease, in a normal apocalypse you've got yer standard diseases, in a nuclear apocalypse, they have that mutation thing, except, well... viruses and bacteria are single celled, so they'll mutate in this same radiation at a much greater pace, and don't get tumours.
Meteor Strike... I'm pretty sure you mean "Asteroid strike", a meteor is something completely different. Either way, this sort of thing only comes in two flavours, the "everything's fine, no one's hurt" variety, and the "oh shit everyone dies" variety. There is quite literally no way to survive an apocalyptic asteroid collision, short of living in a bunker every second of your life. (Simply put, we can't detect these things until they actually hit us, as they travel so fast)
Robot apocalypse! This seems plausible. And would probably suck pretty bad. I don't have much to say about it other than that.
Economic Apocalypse! It's really just anarchy though, but there's a lot more people out to get you than the other apocalypse, so that kinda sucks.
Global Warming - Oh no! The sea level has risen by 6cm! What a disaster! Beaches will recede by a few meters! How will we cope![/sarcasm]
Biblical Apocalypse - So, wait, God botherers will all leave the earth? Then we get a competent leader? (sure, he may be the son of Satan, but hell, it'll be better than any of the party leaders over here! =D ) Holy cow! Where do I sign up! =D
