UCI, UCD, UCSD, and SLO for Biology

How is the program compared to other colleges like UCSD and UCI? Because of the smaller town for SLO, would I have even more difficulty finding experience in the Biology field via internships compared to UCI and UCSD? Or would lab work also be difficult to find at SLO? I am not sure if I would be trying to get work right after finishing undergrad due to the little opportunity without grad school, so would grad schools look at SLO as “lower” than a UC like Irvine or San Diego?
