Personally, I prefer the pistol grip - loading weakhand. The pistol grip allows you to contol the cant while reloading easier.
I also feel it makes it easier to drive the gun.
As far as felt recoil.... most everyone shoot is 2 3/4 wimpy birdshot and low reciol slugs...
I prefer the pistol grip for transitioning from strong to weak shoulder.
It comes down to knowing how to use what you have.
