As a Maine native who went to UG in Boston, my vote is for UMaine. It's the big fish in the small pond of Maine law, and after a few years at a firm like Bernstein Shur or Peirce Atwood, you could go elsewhere in New England (although you might not want to, as life in a town like Portland can be pretty sweet.)
If you go to Suffolk, for your first job you're up against a half dozen other schools, just in the Boston area alone.
