aimatdeer,
I can only speak for the Dura-touch. I have a BAR done in Dura-touch and it's holding up well. Care? Wipe it down with a soft cloth and put it away. I have tried to scratch the coating with a key and could not do anything but dull the surface momentarily. It handles well in high humidity and it's easy to care for. I am having several of my gunstocks dipped as we speak.
