Harvard vs Carnegie Mellon

I was admitted to both the Harvard and Carnegie Mellon pre college programs, but I am having a difficult time choosing which one to go to. All my life I have wanted to go to Carnegie for college and have visited the campus a lot of times since my dad went there, but I was advised to go to Harvard because I will be able to see a different campus as well as be apart of a more intensive course, however I am still not sure what to do :confused:
