Even though I love my 20s there is no way they are hare or even wood pigeon capable. Now add woodcock and the ability to use disperser loads, not available in the 20, and wild boar and slugs and the 12 is the undisputed do-it-all shotgun simply through the variety of available ammunition. Factor the licensing buraucracy and discouragement of multi gun ownership and you can see why the 12 wins.
I still love my 20s though and own several but only one 12, maybe bcause rabbits are my favorite quarry.
