UCSB or UCSD Pre-Med

Hey guys, after 2 years I’m finally transferring out of my CC to either UCSD or UCSB. My major is molecular biology and I I plan on going to medical school. Could anyone provide me with some insight of what school I should pick, I know UCSD is higher ranked but i’m looking for a school with great research that I could easily participate in as an undergrad. Also, if anyone could provide me with some info on how the professors are at each school that would be great. Thanks!
