Joseph, are you a Gadol Hador? Do you personally have a chavrusa in Brooklyn with a Gadol Hador?
If you have a congregation to lead to Brooklyn by all means stay there. If you have a direct connection with Rov Moshe and learn with him personally on a daily basis by some Brooklyn-olam haba connection, stay there. I think your personality would do better in a huge hareidi concentrated location in the tri-state area.
There are other people who would do better leaving Brooklyn and Queens for smaller towns. Sometimes there is pressure to be in those places and they dont even consider living anywhere else.
