I interviewed at both places, granted this is 5 yrs ago but I doubt that much has changed. It all depends on what your interests are. UNC is an academic place, Beaumont is a community program (although they are an academic powerhouse in spine). Beaumont is one of the best clinical residencies in the country, hands down. They have something like 12-16 ORTHO rooms running daily. Incredible volume of surgery. Residents rarely if ever double-scrub. I would give Beaumont a very long hard look. It's a gem of a program.
