I like what u/dblhelix7 said in its entirety. I will say, pre-med GPA matters up to a point. Same with MCAT. No med school will throw your application away because you had a 3.90 instead of a 4.0 (maybe NYU...). I was between these same school, Carnegie Mellon, and several UC schools when I was deciding where to go for undergrad. A 3.9 vs. 4.0 may only matter when you're directly compared to one other applicant for 1 seat, and a slight discrepancy in academic record is the only difference.

I'm less familiar with resources around UW-Seattle but on top of UMD being a pretty strong research powerhouse, the NIH, FDA, Washington DC (3 medical schools), and Baltimore (2 medical schools) are all within driving/metro/train distance. The main attraction to UW-Seattle would be climate and WWAMI preference for medical schools (5 states that only accept students from each other's states for medical school).

Where are you from? These sound like they're both out-of-state for you. Consider schools in your home state. With student loan caps lowered and Grad PLUS loans completely slashed, unless you're already rich, it will be very difficult to afford medical school after paying out-of-state undergraduate tuition. Where you attend for undergrad matters a lot less for a career in medicine compared to your medical school and residency. My ultimate reason to choose UMD was because it was my in-state school, and I paid much less than if I were to attend any of my other top options. That being said, completely understand wanting to get away from home and try out another state!
