They have a good reputation here in Georgia. But again it is just a name. Each subdivision or section of a subdivision and even each house has different builders on the project. Not only that they are generally under a new LLC ever 4 or so houses.
The name is really nothing but a project management company in most cases. You may have a great experience or you may have a bad experience.
My advice is to wait for the house to be built then put in your offer after completion. This market isn't really any rush.
Give me a surfboard and a hammock, some fresh fruit and veg, a fish or two and I am happy for life. I don't need much of a roof over my head to be happy.
