NC is a wonderful state. Been there twice. I like SC too. The problem is that NC also has winter. I'd prefer to avoid winter entirely if I can.
Inland SC, NC, GA have a plus - it’s much less rainy / humid than the coast and Florida, despite being hot I feel it’s more pleasant to be outside in summer. Unless you are right on the beach, Florida and the gulf or Atlantic coasts are unbearable in July or August.
To me that benefit is worth the trade off of occasionally getting cold. But, I’m still warm enough to grow palms and citrus and our ground doesn’t freeze.
