I've never had an interest in a dual-comb razor, though I have purchased the same razor with an open comb base plate and safety bar plate of the same gap - like the Razorock 68OC and 68SB.
I also have a few vintage OC razors which I thought might be better suited to longer growth, but have not found much utility in them as i rarely let my beard go longer than two days.
Besides that, if I ever need to shave longer growth, or a true beard, I would probably use an open blade, like a straight razor or shavette for the first pass.
All of which I suppose means that I have no real practical use for any open comb and only own them for occasional use and a bit of variety in my collection.
