I'd hate either one of those, I find environments that are mostly concrete / grey, hard, square, man-made crap bleak/depressing as hell. And the atmosphere in those places isn't very healthy either. I don't know which I'd hate more. I haven't been in LA since Windows 3.1 was a thing, and I've only driven through part of New York. I think LA might have the worse atmosphere even though it's smaller, and I think people are probably more open/indifferent to weirdos in New York so maybe I'd feel less embarrassed and anxious.
