Man was not created equal, so recoil is perception. What is comfortable for Tom may not be for Dick or Harry IOW. Perceived recoil can be reduced with things like grips/stocks made from recoil absorbing materials, those made to specifically fit the hand/stature that will shoot it, brakes, etc. If you want an advanced comparison that is not just perceived recoil, there are endless formulas and methods, most can be found on-line, that can put numbers on recoil for any firearm & load. Even so recoil still comes down to momentum and energy. In simple terms momentum is the mass of the bullet X its velocity equals the mass of a fiream X its veloicty in the opposite direction when fired and before the bullet leaves the barrel. Energy leads to a different answer based on right after the bullet leaves the barrel. Worth the time to run them if you want a real answer to compare them rather than one that is based on perception of somebody else. HTH
