I have both and have honestly used both very little. I would say BSD gets the nod in looks and Profiline is more spray wax like with likely a little more protection. I believe the intent was for one to be a detailer and one to be more of a spray wax but guessing the difference overall is minimal and hard to tell if you're regularly washing and applying some form of protection to your car.
BSD is a forum favorite around here and the cheaper option.
