I'm with Brian on this one.
In the golden age of tina making. The craftsmen and women who made the reeds, reed pans, bellows, etc went to whichever company would employ them. Simple economics really. So, comparisons just don't work. I play a Wheatstone, because it's what I've got.
Have I any idea who actually built the various parts? Nope. But the people who made the component parts could well have been applying their skills to Lachenal, Jeffries or whoever the following week.
A craftsman is just that. If the money was available they would take the best offer. (Why wouldn't they?)

Obviously nowadays the likes of Colin Dipper and Steve Dickinson (Wheatstone) are making "bespoke" instruments as a cottage industry, to the requirements of their clients.

So Like Brian. I'm out of this convoluted thread that essentially has little point to it.
