I would like to one day hunt South Carolina, but I would probably pick TX if it were me just for the unique experience. While timing can make or break a hunt, sometimes even in a turkey paradise, I have yet to see those TX Rios readily want to do the death flop very easily like it is often assumed. They can be as skittish as any turkeys. The best advice I could give anyone that hunts Rios in TX for the first time is..... If they are responding well to your calls, even from what seems like a sizeable distance, your higher percentage for success is to sit tight because they will cover ground and cover ground fast when they decide to come in. It's easy to bump them if you don't. They tend to cover a lot of ground each day.
I think the low country of South Carolina would be cool to hunt, so you could plan on that for next year maybe.
