I am familiar with a few of the programs:
1) Orlando: ditto what was said already, very laid back, nice town, great experience. Great community atmosphere. Large case load.
2) Medical College of Georgia: town stinks if you are single. Also known as "Disgusta" by the locals....great Master's Weekend. Strong DO presence, not the top of my list. Went to med school here, had to get away.
3) Atlanta Medical Center: Very busy, privately owned inner city community program. Grady seems to get all the crap in town, AMC lots of blunt trauma. Rotate away your 3rd and 4th year, one on one with great Atlanta attendings. Residents seem VERY happy. Interviewed here and really, really liked it. Almost made the top of my list but pushed by my wife to rank closer to her home higher. New chairman is great, very interactive, and taking the program toward a more academic focus.
4) Emory- Bigger name in the area. Huge, Huge volume of trauma. Typical inner city program, hospital lacks funding, OR staff is often rude and NOT in any type of hurry to turn rooms, so you operate LATE. Great attendings, great Spine guys but they can be jerks and there are fellows as well. Research facilities VERY available if that is your thing. I think the operative experience and clinics (which there are LOTS of) help you in decision making because there is little supervision. Good for decision making, bad situation in my opinion. Didn't rank them becasue of this.
5) Greenville- Plush, excellent staff. Very private practice like. best benefits of all programs, especially the food court/free meals! Cheap real estate, very affordable town. Academia in a private setting.
Overall, most programs will provide you good training. Find a place you feel good at, and hope you match there!
