Assuming the question is "after I didn't die in the initial catastrophe", global pandemic seems the safest.
Germs hit all people relatively equally. poor people will probably get hit more due to overcrowding or lesser access to cleanliness that prevents infection.
That means, the remaining survivors come from all walks of life. A mostly even spread. Statistically, I'm smarter than half of the current population, and would retain that advantage. From there, the surviving population doesn't have any statistical advantage to out survive me or kill me. So I'll be useful in the new society and have a higher position.
Whereas, in a zombie apocalypse, survival is mostly due to better skill in combat and running away. this means more of the people who remain will be more suited to violence or running away from me than I am. This diminishes my chances as I could be the slower or less fighty one to get taken down.
In the Rapture, all those in the Winning religion disappear (if I recall my Simpsons lore, it's the 7th Day Adventists). Let's pretend the Raptureful deity isn't that picky and chooses all the good people, not just folks who went to a certain church. That means I'm left behind with all the "bad" people. Aside from what that says about me, it means the rest of the population is liars, thieves and murderers and can't be trusted. That makes for a very dangerous world to live in, where isolation is your friend.
In the Ice Age, I might be OK. I live in Texas. I'm from Minnesota. In all likelyhood, TX becomes the new MN, and I can handle that.
Asteroid collision is worse than Ice Age. While I can deal with a simple shift from hot to cold. The asteroid is going to cloud the skies for years, preventing crop growth regardless of where I am. I have no geographical advantage. I'll be scavenging for supplies and freezing all year round.
In the Invasion scenario (robot or alien is pretty much the same), I don't like my chances. The monsters are likely to do a purge or round-up. So there ain't nowhere safe. You can't go to the country and build a compound with crops and stuff. It'll show up on scans and you'll be caught.
So Pandemic is the best:
same diversity of people puts me in the upper half* for skills and smarts
survivors don't have a heavy concentration towards evil or violence
no significant post-event to deal with (not counting rats)
*by upper half, I mean I have more skills and higher IQ than the average human, which means I can do more useful things than the average person, not that I am some elite super human, there are people who can do a lot more than I can.
Being in the upper half of skills/smarts is going to be an advantage. People who can fight, shoot, hunt, farm, build/repair are going to be valuable. Especially if they can do all of those things. As a tendency, people who can farm, tend to have some experience in shooting, hunting and building, so they already have a leg up on the competition where self reliance is a key to survival. If I only knew how to program computers, I would be screwed.
