Took some photos of the Exclusive The Black Series 6-Inch Rogue One 03: K-2SO (Fan Channel) and the K-7R1 (Disney Droid Depot Set) KX-Series Security Droids for comparison.
The figures are identical sculpt wise, but do have different paint decos. Personally like the look of the K-7R1 better.
You can check out these photos and I will get the rest posted to the product pages later on.
