IMO my two cents
If you can get into Temple or Tulanes Anatomy program(note not pharmacology the anatomy one which requires an MD WL to even apply) take it don't look back. I think both have 90+% of their grads get into US MD programs. No brainer.
1) Cincinnati:

Read about it. The vast majority of their grads get into US MD programs. It's small, very respected and does well. Also you get to establish Ohio residency if you need a gap year after which is big. Ater Temple and Tulane its for my money the best program. You know what you are getting here. They specifically show you exactly how well their grads do which is very rare. I think probably on average at least 80% of their grads get into US MDs. Do what you need to here, you'll be in good position. And Cincinnati if you get in is a really good med school. This would be my top choice for anybody looking for an SMP.
2) Georgetown: They still have a great rep. The majority of their grads get into US MD programs. The program is brutal and hard as hell, if you dont have work habbits and have recent good grades in UG you are just asking for problems here, but if you get through it and do decently, you are putting yourself in a solid spot.
I don't know a ton about other programs. I think Tufts places the majority of its grads into US MD programs and about 30-40% in Tufts med. It's a solid option although they are kinda vague and tight lipped with how well their grads do which gives me pause and why I would go G'town or Cinncy over them.
The days of programs having strong linkage are done. Eastern Virginia and Toledo's linkage ie percent of SMP grads who get into their MD program has gone way way down in recent years. Its a watered down product, I wouldn't recommend. Same with Drexel and other lesser known programs. Rosalind Franklin is one I think might head down this direction although for now their linkage seems still pretty decent.
All in all given how risky SMPs are and how watered down alot of programs are, I really would only bother with a few of them. If its not Cincy or G'town or perhaps BostonU/Tufts/Rosalind/Loyola(and even some of these I'm meh on), I don't think I'd really recommend it in most situations.
