That's tough because they're completely different experiences!
If you want characters and/or a fantasy-type setting, definitely Artist Point. The menu is much more limited so if you have picky eaters look at what's available and make sure everyone would be happy with the choices. With the characters and classic Disney-esque theming, it might make a good last night dinner so you can soak up the stuff that makes Disney special.
If you want a LOT of really good, southern comfort food in a relaxing atmosphere, go for Homecoming. Homecoming is one of my personal fave restaurants in all of WDW.
