I did Post-bac at PAFA. It was a great experience. The grad chair, Didier, is an amazing person and educator - not to mention super well-connected and a successful artist. The visiting artists are top notch and there are some other really great faculty members as well. Definitely a program on the upswing.
The studios are some of the nicest I've seen, most 2nd year MFAs have big-windowed private studios with a gorgeous view of City Hall.
Also, there is an annual NYC show curated by Didier and Josephine Halvorson comprised of student work from PAFA and BU. This year it's at Anna Zorina (in the past it's been at 1969 Gallery and On Stellar Rays).
I'm not too familiar with Ole Miss but that's my 2cents on PAFA.
