Face a million Legendary Boatflies or 10 Legendary Deathclaws. Feel free to add your own since my stupid one is the only one I could think of.

I like bunnies.

Well 10 legendary Deathclaws of course, I won't have ammo enough for 1.000.000 legendary Bloatflies.

A more realistic situation, would you rather face 20 pre-patch Cazadors with mid-tier gear (no miniguns or other high tier automatic weapons, only mid-tier stuff) or be stuck in the Sierra Madre for two ingame weeks in which the Ghost's heads won't pop, which means that no matter what you do they will get up and start hunting you again if you haven't hightailed it out of there.

One is a quick situation of complete and total panic-attack whereas the other one is a slow creeping long-lasting fear.

I think I'd choose Sierra Madre, cause pre-patch Cazador's are scary.

That would've made the DLC so [censored] awesome.

I think the million legendary bloatflies will kill themselves with their blasts. Once most are killed I just have to use a wall for cover and pop out to shoot.

Yeah, that Sierra Madre situation actually sounds like a lot of fun.
