It's a matter of personal taste. Back when I did some shotgun hunting, I preferred a SXS to an O/U by a mile. I lost interest in birds a long time ago, but I still have my 16 ga Winchester 24 and my little 18 inch barrel Savage 311A.
The little Savage, loaded with 00 buck, still takes a lot of rides with me in my truck.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
