I have zero experience with the Prostance, but I do own a V-Ride as well as a Gravely ZTR with the X-Factor deck. I can easily SEE the distinction between both decks. Of course this is my opinion only, but I truly believe the edge goes to the SCAG Velocity deck. I am thoroughly pleased with my V-Ride, so much so that I prefer to use that machine versus my Gravely and other SCAG machines.
