Congratulations on your acceptances!
Last month, I was in a similar dilemma between UCSF and UCSD with a scholarship (reverse though, I first got into UCSD and then into UCSF off the waitlist; interesting how Einstein took you from the waitlist and then gave you $25k/year; they must've decided they really like you!).
Anyway, I ultimately chose UCSF. While both match similarly well into California and have excellent research, community involvement, teaching, etc, I went to visit both schools to see which was a better "fit" for me.
What did fit involve? The most important part, for me, was moving to a new environment. I'd been born and raised in SoCal and thought that moving to NorCal would encourage some personal growth that I wouldn't get in my home area (I've already felt the challenge of the new environment while searching long and hard for housing in SF, which wasn't easy!). Other stuff, such as better global health opportunities and arguably more innovation at UCSF, also figured into my decision, and ultimately, I found that I preferred UCSF in the things that mattered most to me.
Go with your gut. I knew I'd be so happy at both places (and probably happier in terms of chill, sunny, laid-back quality of life in SoCal), but I just felt that UCSF was where I should go.
Of course, do your whole pros/cons list. Here's a resource I found through UCSF that looks pretty self-explanatory and campy but seems actually really helpful:

How important is it for you to try out a new environment? Are you interested in academic medicine, research, private practice, policy, etc? What about the clinical training at both hospitals? Ask the questions you think are most important, and you'll figure something out.
Good luck with your decision! You can't go wrong with either
