For motorcycling primarily, I have a pair of White/Hathorn Open Road engineer boots and I have a pair of Wesco harness boots. They are both size 10D and I can tell no difference in fit or quality of construction. I think the leather on the Wesco's may be just a bit thicker, but not much. I also have a pair of White Smokejumpers and the leather on those and the Wesco's feel just the same. Both companies make an excellent product in my experience.
