For what it is worth, a couple weeks ago I asked my cousin from Minneapolis, MN (playing in USHL this fall) if he or any of his friends/teammates used FBV. He very quickly said, "no". I know that isn't very scientific, but he is an elite HS player (transitioning to Jr A), in arguably the biggest hockey state in the US, and he was confident that no one he knows is really using it. Now I have tried it myself and I liked the sharpening, but I think most important is even edges and good finish. I really wonder if someone had a high quality ROH and a high quality FBV if there would be a noticeable difference...or if FBV gets preferred by some folks because the sharpener was forced to ensure even edges, etc due to the nature of the shape.
