I do not know specifics of these two.
On the other hand, the strenght of your UG academics wil mostly depend on you and not the place.
Also, having Med. School at university or not has nothing to do with the opportunites for Medical ECs.
Here is an example of my D. that could be used as supportive points for my statememnts. She graduated from in-state public UG in OH. Her university does not have a Medical School. She had plenty of opportunities there. Since nothing was available to her in our hometown during summers (dead city!), she did ALL of her Medical ECs (and others) during school year at college. All were long term, mostly 3 year commitments. It took nothing, simple email and short interview to get an internship position at Med. Research lab at her college - she did research for 3 years, poster presentation, great LOR from person in charge. She was volunteering in her college town also for 3 years. After graduation, D. and her pre-med friends had great choices of Med. Schools that they were accepted to and some had hard time deciding (including my D.). They are graduating from Med. Schools this year and while I do not know personal stories of each, D. just had a very successful residency application cycle, matching to her #1 choice.
It is YOU, not the place will determine your future. Choose the UG that personally fits you the best, nobody can tell you which one is a better fit.
