I'd take pitt, others made some good arguments for pitt below (vs GT) and I think of pitt as a med school that has a really innovative cirriculum, a great hospital (#15 i think in the last usnews hospital ranks) and thriving research in all areas. great surgery depts. Talking to my advisor this week about pitt and she thinks that it is one of many schools that a lot of premeds at my ugrad school won't consider since its not on the east coast and a lot of life-long east coasters have this severe bias. Now tufts is a good school, but if you don't have need to be in boston I would say pitt all the way.
