I will (very likely) be attending Wake in the fall, so I'll offer a few thoughts too. With the new Innovation Quarter initiative, the school really emphasizes entrepreneurship and biotech start up culture and I think that has a really interesting intersection with medicine. For me, that was a very big plus. I think Wake is also better for those with interests in biomedical and clinical research. The Institute for Regenerative Medicine is a very top notch program. The location in NC is very close to the Research Triangle Park (Durham, Chapel Hill, Raleigh) which is a great hub for technology and innovation so there are lots of opportunities to collaborate with other universities and industries. (Only about 1.5 hrs drive along easy, little traffic highway) The town of Winston Salem probably doesn't compare to DC but let's be serious, few cities do hahah! But the city is being revitalized from prior tobacco manufacturing hub to tech hub and the government and university seem very passionate about the cause. So living costs are far far more manageable. At Wake, the student body is organized into houses with faculty membership so I can imagine that every one is super close. When I interviewed there, I really enjoyed it so much and everyone was very very kind. I think since GT is a bit sprawled over the city and Wake is in a smaller town, I can understand if the student body is more close knit.
Georgetown is also a great school. I was looking into this school as well and although I didn't get to interview here (that would have made my decision a lot harder haha!) I have a close friend who goes there. Living costs are really really steep although DC has a wonderful vibe. Since GT is a more liberal arts school I felt that that clinical research is better at Wake. Also the general vibe seems that GT has a more campus feel and Wake has a more city feel since the medical campus is separated from the undergraduate Reynolda campus. The Wake med campus is very close and convenient whereas GT is far more sprawled. Not sure if that matters.
Will add more if I can think of anything
