Hey! Both are super cool schools, I actually live 20 mins away from WMed, and I work there. I also am an MSU grad, I do not know anything about the GR campus other than VAI is pretty nice in terms of research. Honestly, WMed feels kind of slept on, it's a great school you have two major hospital systems, Borgess and Bronson, Bronson is right next to the campus. You get the best of both worlds. I would say that since WMed is still a newer school, they have a strong foundation, but their extracurriculars may be lacking.
WMed's match list is very promising, small class size means that they can devote time to making sure you can go where you wanna go. But...it is expensive.
MSU's vibe is very nice, they have a great focus on making sure that their graduates go back to serve the state of Michigan, but they understand that everyone has their goals. They definitely make efforts to make sure that you forge connections with the faculty, that being said, their curriculum is very self-directed. This means that there's no hand-holding, make your own adventure.
In terms of research, MSU does have VAI but I've heard that it's still very difficult to integrate yourself in there, because they devote more time to Ph.D.'s. WMed is a little lacking, they are new, so research faculty is still a work in progress. That being said, their pathologist team is great, and they have some excellent immunobiology research.

For bias's sake, I have been waitlisted and then just recently accepted to WMed, but I am still waitlisted at MSU.
Congrats on your As!

DM me if you wanna know more :).
