Columbia Graduate in CS or Brown Graduate in CS

My daughter got into Columbia and a week and a half later got into Brown. I honestly was shocked that she got into both programs and now we have to decide. We visited the Brown campus and coming from NYU the small condensed quality of the campus was jarring. I know she will have to choose based on her classes and focus but when looking at each school they are very different- only I wonder what differences there are in the graduate programs. Any thoughts on the Graduate Computer Science programs folks?

Columbia ranks higher for Graduate CS on US News (#13 vs. #20).

For PhD or theis-based MS programs, the primary consideration should be the professor/advisor in the field and subfield she’s interested in and would like to do her thesis with, not the school.
