I'm in the tire biz, but you'd have to tell me a lot more about your driving style, ride preference, etc., before a recommendation could be made. The X is performance driven, especially the Advance. Seeing you are in Atlanta I assume no snow? Or do you venture north or to the mountains? How much of a priority is tire life? The more sticky the tire is for a tight grip the softer the rubber and shorter life. What price point, or doesn't it matter?
There are a lot of solid tire models to choose from today and as Pkrface pointed out, ultimately the right tire model for you will depend on where you live, how you use the vehicle and what performance attributes you expect the tires to deliver. Tires are a product of compromise which is why more info is needed.
