There are a ton of "good" southern ortho programs. Duke is of course a good program, just depends on what you are looking for. Other good programs include: UNC, Carolinas, Campbell Clinic, Greenville, Florida, Miami, UAB, and Mississippi are all very good training programs.
Now if you are asking about sports experience, I can not comment on many of these places. My guess is that all are adequate. Campbell's is a good sports experience, I am sure Carolinas and Florida are good as well. I can not say about the rest.
