If you like the plow grip the BFR is the better revolver of the two. But it also cost more $$$$. My impression of the BFR's after owning 3 is they are like a Ruger on steroids. IMO the BFR also has a smoother action and better trigger if you compare them against the Ruger.
But if you have to spend the money to change the grip shape then stick with the Ruger.
