I lived in Monsey as a bochur for a few years and continued to visit many times over the years and I always marveled myself at the pleasant natural integration of the litvish and chassidish elements. In so many shuls, you’ll see all types davening together. It made a strong impression on me then and I always recall it fondly.
I don’t like getting into specifics about a specific group or place here. It’s a great place to live if you need to be close to the city. But property taxes are through the roof.
Jewishly, you’ll have everything you need. I have found that the more I deemphasized the groups- I have become more enriched from benefitting from all what each has to offer to our Avodas Hashem. Monsey, for me, was the beginning of that approach.
