I pretty much agree with what others have already said, but have added my two cents below [in brackets]. I've been growing fruit in N. Georgia and Piedmont North Carolina (RDU area) since 1979. To the very nice list below, I would add:
Enterprise, which has done very well from a tree health perspective and is quite vigorous. However, it is not the best apple for fresh eating. Texture is a little dense and not as crisp as some of those below, and taste is good, but not great, in my opinion. However, it ripens about when Goldrush does and is a good all-purpose apple.
Honeycrisp- Yes, Honeycrisp. It is not recommended in our area, but the problem appears to be it's poor calcium transport capability. If you are willing to foliar feed the young, developing fruit with chelated calcium, then you will get crisp apples with a well-balanced flavor profile that may even be superior to the best Honeycrisps grown in its native Minnesota (please no flames from MN- you grow great Honeycrisps, it's just we can do it too, with some extra care).
NY 75414-1: I don't know if Cornell will ever release this one, but you can get it from Raintree Nursery. It overlaps in ripening with Liberty and has had very little disease of any kind. Like Liberty, its quality suffers if you get a heat wave when it's ripening. Otherwise a very good flavored and textured apple.
MAIA has some numbered selections that I've trialed that do very well here and have some great flavor and texture profiles, but you'd have to talk to MAIA about getting scionwood. I sent them a detailed report on the performance of their selections here, but never heard a peep back.
Heirlooms have generally done poorly here for me. 'Joseph' looked promising for a while, but as the years passed, seems to underperform on average. Ribston Pippins were great tasting, but I got tired of the severe fireblight and removed them.
I have an unnamed family heirloom that is very healthy, precocious and good tasting, but it is not crisp, so I doubt that I will ever release it.
It's really too bad that we don't have an apple breeding program for the Southeastern U.S. Maybe we should start one ;)

[The short stem and the high productivity makes thinning a bit more difficult than many other cultivars, but maybe because that's because I hand thin (insane, but it works). This is one of my favorite cultivars, including for flavor, but some years it misses quality metrics badly. If you get a heat wave when they are ripening, flavor and texture suffer considerably. Despite this problem in maybe two years out of 20+ so far, most years this one is an excellent apple, even in our semi-tropical climate.]
