I find Homecomin to be easier to get reservations on Open Table...the Disney app can be very difficult. Walk up can have success sometimes, but I prefer to just get an Open Table res to be safe.
I think it's a great restaurant. Is it the best southern food in the South? Of course not. But it's easily the best southern-style food and chicken in Disney World, so that makes it an easy pick for me. It's solid comfort food, tasty, done in a good proper southern style even if you can find better at places back home. If you and your husband enjoy southern food, then I think it's still a great option, unless your requirement is that it be better than any southern-cooking place you've ever eaten. If the requirement is tasty fried chicken, good biscuits, nice traditional southern sides, and bottomless sweet tea, then it's one of the best choices in Disney.
I've had much better Mexican, Italian, Japanese, German, French food, steaks, burgers, etc than what I can find at Disney, yet I can still enjoy the best of those at Disney World - I'm not comparing them to the best I've ever eaten - I'm simply comparing to what are the best of each of those I can find at Disney World.
At Disney Springs, I like Boathouse, Enzo's Hideaway, and Summer House along with Homecomin. Morimoto and Raglan Road are good for occasional visits, D Luxe burger and Chicken Guy decent for quick food. Frontera can be good - I've had very good meals and so-so, so just need to pick certain things on the menu. Same for Wine Bar George - a few really good dishes there and great wines. Appetizers at Jock Lindsey's, and sometimes just the easy casual serve/American pub stuff like Rainforest and House of Blues when I don't feel like thinking hard.
