Thank you all so much for your time, input, and thoughtfulness!! This past week I've been talking to my family, friends, current med students, and advisors to weigh my options carefully. Just to address people's comments: First, I agree that UCLA has several advantages like location, finances, curriculum, etc., and given the areas of medicine that interest me, I need time to focus on research, making the Discovery year a convenient opportunity for me to increase pubs. I would like to add that from my understanding, we still have to be in clinic two half-days per week during M3 which I think is good because I had also initially been concerned about how my clinical skills would be impacted by a research year.
I also read through that interesting thread and I'm glad I got to hear perspectives from multiple students about their experiences. Since no med school is perfect, what matters most to me about any program (besides financial aid lol) is learning "what are the things that students don't like about their school?" in order to decide if I can live with those flaws or not, but up until now I found it a little difficult getting any straightforward complaints/criticisms from students at any of the second looks and admitted students events that I attended. Learning how UCLA students have handled the condensed pre-clinical curriculum (which is the same length as UMich's), shelf exams, step 1/2, etc.---both the good and the bad--is exactly what I needed to hear. It has served as an important reminder that self-directed learning and pushing myself beyond a set standard will be necessary all throughout med school (and beyond) regardless of where I go.
In the end, the one thing that has taken up considerable thought for me is the distance from home. However, since my family is not from Michigan, I'm going to have to get used to the idea of relying on FaceTime and zoom to check in with them either way as a 5 hour drive (10 hrs round trip) is not something that can be done frequently. And, knowing myself, as I get older, the urge to remain close to home will only grow. Going to UCLA might very well be an opportunity of lifetime before settling down in the midwest. So even though this is not easy at all, I will likely be withdrawing my acceptance from UMich. I'm going to give myself the rest of this weekend though to think it through because committing to this huge life-changing event is nerve-racking!
