There is another thread with this same choice. I think there is a misconception that Brown lacks rigor. This is not true, not at all. Don’t confuse freedom in the curriculum with lack of rigor. From personal observation, I would say, however, that Brown students tend toward the cooperative and supportive, and in our experience that extends years after graduation with a great network.
I know both schools and have lived in Philly. I confess to being biased. Brown is my favorite school. One of my kids thrived there and continues to thrive through the Brown network of alumni/ae , well after finishing.
Providence is a small city, but Thayer St, is fun and Providence has been “happening.” Many people have moved down from Boston. The coastline nearby is scenic. It isn’t that far from NYC. Then again, I love Philly too. I think you have a clear choice in terms of location.
