Impressions . . . we personally liked SMU the best but TCU felt the most comfortable socially.
We’ve only visited SMU so far. Dh and our oldest two kids went to the Springfest event and were very impressed. We also have many friends from our college days who graduated from SMU and are doing very well - especially the one who graduated from Cox business school.
