I thought JH Adriatic is a good variety because it seems to be easy to grow and reasonably prolific in a wider variety of climate. Sorta the White VdB.
Brunswick tends to have people pleased with the flavor. It's not favored because it does not produce quality fruits under a wide variety of circumstances. Specifically, it's really for very medit climes, with dry and less humid air during fruiting. Kadota has been around for millenia, produces plenty of fruit, but really good tasting fruit requires an especially good year, weatherwise. Yeah, probably should ditch those two once you have growing starts of better figs. Brunswick should do okay in SC, though, maybe, depending on the strain.
Also, I think you could also consider Italian 258, or I-258, which is slightly similar to Black Madeira but more vigorous, productive, reliable.
