The problem with seperating scratchbuilt into its own catagory is that there isn't one single way of scratchbuilding.
As my earlier questions aluded to with regards to the body for example, there are lots of ways to go about making it. These days you can go the 3D modelling route as out Russian friend on these boads does or you can do it the more traditonal carved way.
not all scratch built models have working steering or suspension.

That is I asked about where you would draw the line.
If you think that kit builds and scratch built are indeed too different to be comparable then that opens up the ones I put forward as also valid catagories. I mean, how can a guy who cuts/glues plastic compete with a guy who machines metal? How can a guy who carves a body compete with a guy who makes a 3D print or otherwise machines a body?

It sounds to me like you are looking one extreme end of what scratchbuilding can be and then comparing that regular kit building. I on the other hand believe that the majority of scratch building is more like regular kit building and scratch detailing which is why I said that there is little difference between the two.
