Absolutely one of my favorite airports to have a layover at. This place is easy to navigate, tons of shops and food choices as well. There's a lovely USO top floor of the atrium and if you like sushi this airport offers a good selection both to go OR as a fine in option (also located in the Atrium).
The only down side is that there's no Delta lounge. For this I am sad panda but it's not enough of a detractor to downgrade the review.
If you have the option to swing through Charlotte NC as a layover, do it. You'll like this place
