I'd like to answer myself in order to make this thread useful.
I've been on Monthly4G for a few months now and coverage in Rockland is fantastic. Low signal areas are very comparable to Sprint, and their aren't many. Network speeds are pretty great, my peak being 28mbps down in New City. My average down speed is between 6 and 11mbps.
I work in New Jersey, and it's great there too.
