Cooper union vs git vs cmu, what is best for mechanical engineering?

I’m looking for a good mechanical engineering college and these are my top choices, assuming I can get into all three which if them is the best

You can get a great education at all 3.

3 very different schools. You need to visit to see what you are comfortable with.

Cooper is tiny. 1k ugrad.
CMU is small. 7k ugrad. 11th ranked mech eng.
GT is medium size. 15k ugrad. 3rd ranked mech eng.

You would get more individual attention and resources from the smaller schools… but you will pay for it $$$.
