UC Berkeley vs. Cornell Pre Med?

Hi everyone, I am currently a senior in high school having some trouble choosing a school. I was accepted into UC Berkeley and offered a Transfer Option from Cornell University (I can go to any school for a year and as long as I maintain a 3.3 gpa I am guaranteed a transfer sophomore year).

Any advice on which school would be better pursue pre medicine and apply to medical school from? Which school will prepare me best and make me the best candidate for medical school? Any help is much appreciated!!! Thanks!!!
