I've lived in MIllburn for 10+years. Both Maplewood and Millburn are wonderful communities. Close to the city, well served by public transportation and somewhat diverse. Maplewood, Village, the town's center is charming and functional and I wish Millburn's Main street area had the same feeling and as many fun places to go.
But for me, and with taxes as high as they are in both communities, the superiority of Millburn's school system makes it an easy choice.
