Having had an X-200 right next to a KX-200 flipped upside down on my bench, I found the KX-200 to be more neat under the chassis. The X-200 was predictably wired, but didn't have fancy dress. On the K, at least in this example, the wiring was top quality. I've seen others that were hobbyist quality and one that was only prototype quality. I guess for the KXs, the only thing you can be sure of is that you can't be sure of the wiring dress. The assembly instructions do tell you what to do and how to dress your leads to a certain extent, but it was always up to the individual.
