The only one I could find on the market (KATL Atlanta) is Imaginesim’s - I assume you’re referring to this one.
There’s a review on YouTube from FS Elite:
Not sure what the general consensus is about this one - and, more importantly, if there have been updates since that review.
Personally I held off purchasing it since a decent KATL has been included in World Update USA (to me it looks more accurate than Imaginesim’s) - you’ll find a comparison with it in the same review, starting at 5:06.
