Case Western has a stronger VA, where you get many cases. Virginia has a weak, far away, small VA hospital. However, UVa's VA hospital does have a decent faculty member there, but that's just one, so you'll know just his way. In contrast, there are more faculty at the VA in Cleveland but I have no idea if they are uncaring and sloppy, or great teachers.
Against Cleveland is that I know a very stinky and selfish graduate from there. If that program produces that, ouch.
Bottom line: uncertain, but I'd lean slightly towards Cleveland. If you have something slightly unusual in your application, Cleveland might take a chance and take you because they have more residents but a smaller program would probably be able to find 6-8 standard good applicants and rank them higher. For Cleveland's 6, maybe you have to be in the top 16-18 so psychologically, they could put an unusual person in #17 while if you are #17 ranked at UVa, you might not get in. A DO got into Cleveland. (This logic doesn't apply to the top places because they get lots of perfect applicants).
