i'd remove Chicago and DC, and add Philadelphia.
DC is fine but as soon as you leave downtown it becomes barely better than the american norm (the subway is honestly hilarious, "downtown largo" yeah right lmao by that logic NYC is "downtown USA").
Basically the same with Chicago, it's "fine" but very quickly the subway just stops and it's back to an endless sea of dogshit suburbia.
NYC and Boston are the only ones i would confidently call "actually acceptable", and even then Boston only qualifies because the downtown-fenway-brookline corridor is effectively a transplanted piece of NYC..
Like, fuck.. Literally just hoboken is a more proper place than all the other american cities, it's insane.
