Have you visited the campuses? While CWRU and CMU have similar student body feel and I believe number, CWRU campus is very spread out whereas CMU is much more compact. You can also take classes at UPitt if something is not offered at CMU as they have reciprocal agreement and are side by side. I did like University Circle area in which CWRU is located but the area of Pittsburgh CMU is located (Oakland) has a more typical college town feel plus you have the city at your doorstep. Plus there’s Pamela’s and their fabulous hotcakes (still dreaming about those). Though if wanted to save the money, I believe you would get a good scholarship from CWRU and so it would be a relatively good value in that respect.
