Cloud City all the way.
It's the only option really. It's just a simple process of elimination.
Underwater city: Aquaman, Namor, the green Snork - all notorious homosexuals. Hey, I'm as liberal as the next guy but that don't mean I want to share a property line with the queens of the seas.
On-water floating city: whoop-dee-****ing-doo. I mean it's practically a floating trailer park. Get your ****ing houseboat out of here Aqua-Cletus. Sail that heap out to the great Pacific garbage patch where it belongs.
Earth orbiting satellite ship-city: Hey, ****ing stay or ****ing leave. We ain't got time for this "orbiting" bullshit.
Lunar city: first off, I'm not taking sloppy seconds from Neil Armstrong. Second, you can stow all that "Magnificent Desolation" claptrap. We know that's just fancy Moon Man talk for "this place is a ****ing dump." Peddle that green cheese somewhere else, Buzz.
Martian city: if Mars is so hot then why do they keep trying to invade Earth? Yeah, it may be the fourth planet but it's strictly third world. Ain't nobody leaving NYC via Ellis Island to get to Ethiopia and ain't nobody leaving mother Earth to go bopping through a Stargate to get to the "Angry Red Planet."
Interstellar ship-city: space wet-backs
I will die defending the land of my ancestors: The Chicxulub impactor landed on us, we didn't land on the Chicxulub impactor. I don't owe terra firma shit.
I wander aimlessly: WTF kind of choice is this? Yeah, I'm gonna pass up the chance to live in a
CLOUD CITY where I spend my days running down uppity condors and emptying my chamberpot on a bunch of Earthbound troglodytes to waste my life as a ****ing bag lady in some Cormac McCarthy hellscape.
