Im actually trying to decide between these two schools as well. They both have similar curriculums and students seem equally as happy. I think it'd be great to go to UC where they have great research opportunities, volunteer service, and international opportunities. They match very well in a lot of competitive specialties and tend to do much better than average on the USMLE. Rush does very well to but the city opportunities just make it so appealing as well. Based on the medical center itself, Rush surpasses UC. If youre interested in peds, UC is amazing. I know this isn't much help, but I'm in the same boat and hoping we can get some more insight. I change my mind daily on where I want to go.
