there is a mix, it is mainly black hat leaning though there are a few modern families think of flatbush or kew garden hills you dont have to wear a white shirt everyday or a hat to shule if that is what you are asking though most people do wear a hat on shabbos and some during the week as well. It is a very warm community where people accept you for being frum and are not so into chitzoniyos.
Please spend a shabbos there, even if you decide against living there i am sure you will have a nice experience. Just a reminder Waterbury near the Yeshiva has more of a mix. In the blue ridge development it so far 1/2 kollel 1/2 working but like i said whichever you decide everyone is nice.
