The issue to me isn’t New York vs every place else. It’s is more of a large community vs small community issue. To me, there is very little difference (besides accents) between the large Jewish communities in NYC, Chicago, LA or Miami. All of those places have large enough Jewish populations to have developed separate communities of Jews, chareidi, MO, chassidic, etc.
Compare that to the Jewish communities in, say, Birmingham Alabama or Omaha Nebraska. There, the most striking difference from big city communities is the fellow feeling that the entire community has for each other. the various denominations of Judaism come together and cooperate in ways that would be unthinkable in places like Flatbush or Skokie. For instance, you will see the local Lakewood kolel receiving support from Federation. Try that in BP!, Heck, try that in Lakewood.
