Williams College vs. Emory vs. Cornell?

I was accepted into these schools and now I have to choose. Money isn't an issue. My parents do not know much about colleges and instantly decided I should go to Cornell since they haven't heard of the other 2. They don't seem to listen to me but they do listen to others. I am undecided but I am interested in pre-med or business. I applied undecided to all 3. What are the pros and cons of each school? Liberal Arts College vs. University? Which one is more "known" in the job recruiter world?
