So I can't speak from personal experience, but my mother received her mDiv from BU (choosing it over Harvard) in the mid 2000s. They gave her full funding and a lot of support during her studies. It was definitely a positive experience for her and fits your liberal vibe. As I believe someone else said you also have access to other universities as part of the program. As part of her degree she worked as a hospital chaplain in addition to a more traditional church setting, so you can definitely get different experiences based on your interests. I'd say wait and see what Harvard gives you, visit both schools, and go with the one that feels right rather than name recognition.
