I am familiar with both colleges. They are both excellent, but are different as @Gumbymom pointed out. Their campuses are also different, with CWRU being an urban campus, not a cute enclosed college campus. Both will offer him a very fine college education.
Does your son want to live in a smaller town, or a larger urban area?
I think either option would be fine…if it’s what your son wants in a college, and you find it affordable. I guess what I am saying is…if your son really doesn’t like the smaller LAC college, then I hope the finances work for the larger more urban school.
