I would say that UNC is one of those programs that doesn't get mentioned a lot, but when someone mentions it, everyone else says, "Oh yeah, they're good too" Reasonable national name recognition (again, Dr. Sheldon and Dr. Meyer certain help in this regard, as well as the basketball team discounting this year
)
Off the top of my head, other programs I put in that category of, often forgotten, but generally recognized as good programs that could make a case for being as good as anyone (obviously I probably am going to generate some controversy here both with the ones I list and the ones I forgot): Obviously any of the regional powerhouses I listed in the top 10 General Surgery thread, plus UC Davis, UVa, U-Fl-Gainesville, Yale, UAB, U-Chicago, U-Wisconsin and U-Maryland come to mind, but the list goes on and on.
You'll notice that many of these are State University affiliated, probably because they thus have better name recognition, but don't pop up as "elite."
Again, I will give 3 disclaimers:
1) virtually any program that is certified by the RRC will give you adequate training, find the program that you fit in well. Thriving at a "second tier" program is far better than being miserable at a "first tier" program.
2) I don't list community programs because my experience with them is extremely limited, however, prestige rankings in general follow Universities. Is this fair? No. Is it a reflection on the quality of education at commnuity programs? No. But that's the way of the world, university based programs are more famous and get more mentions.
3) I don't have first hand knowledge of many of these programs, only the impressions that I get secondhand from the students, residents, and attendings I interact with.
I hope this helps.
