All of my shooting is at game, (no clays within reasonable driving distance). Much of the shooting is done in adverse conditions with a high attrition rate to the gun. I have two different types of gun: Those I can fall on and break, and those I take on flat ground. All are SxS
The disposable guns are inexpensive spanish doubles with straight stock, unimaginative wood, 6-1/2 pound, swivels, tight chokes, extractors, double triggers, 30" barrels, splinter forend.
The keeper guns are mostly vintage Americana. For quick work on small birds, I prefer a 20 gauge in the 5-1/2 pound range with 26-28" barrels, double trigger, mod/IM chokes, splinter, straight stock with some character. For larger game I prefer a 6-1/2 to 7 pound 12 gauge, splinter, straight stock, double trigger, 30" barrel, full chokes. I'll take a POW grip, but the other stuff is mandatory.
I'm of pedestrian means, so I'm more hung up on function and fit than engraving, but as time goes by I see myself trading up. My fantasy gun is a turnbull upgrade of my field grade LC Smith 20 gauge to a deluxe grade look with exhibition wood.
