Cmu or Columbia?

Hi guys, I was recently admitted to Carnegie Mellon and Columbia as a transfer for Biomedical Engineering(Mech E for CMU but might double major). I was wondering if anyone has any inputs on which university I should choose. So far, its to my understanding that CMU has an overall better engineering program but Columbia has more research, job opportunities, and prestige. I was wondering if anybody is currently studying Mech E or BME at CMU and could give me a perspective on how it is. Additionally, I wanted to know how the social life, food, and clubs are at CMU. Any advice would be helpful! Thanks in advance.
