I too love pump guns and I don't know of any bad ones. That said, the following are shotguns I have either owned in the past or still have (except where noted) and are ranked in order of preference:
1) Winchester Model 12 (have used but never owned, but best looking and "feeling "of all of them)
2) Remington Model 31 ( " " " " " , but second best looking and feeling of all of them)
3) Ithaca Model 37 (my first shotgun, loved the light-weight and bottom ejection. Traded it for a Browning Double Auto in 1961. Would love to have one in 16 ga.)
4) Browning BPS (my last-so far!- shotgun, love the heavy-weight for its intended purpose-turkey and waterfowl, the bottom ejection and the tang safety)
5) Winchester Model 97 (appreciate the material, design and workmanship on a gun that was viable in the marketplace for over half a century. Got rid of mine because I found the trigger guard too cramped to use safely when wearing gloves while duck hunting and because I was afraid that steel shot might be harmful to the bore. It had a 32" long barrel, choked full and I've never patterned any shotgun that had a pattern as tight as this one)
6) Marlin Model 120 ( did a good job in mimicking the Model 12. I had a couple of these over the years and, if you can find one, they're good guns. I detest impressed checkering and most 120s had it)
7) Smith & Wesson Model 3000 (did a good job in mimicking the Model 870 but eliminated a jam factor known in le circles that seemed peculiar to Remington. I do regret selling mine)
8) Remington Model 870 (hard to fault this gun but if the safety has to be on the trigger guard I much prefer it to be in the front instead of the rear)
9) Winchester Model 1300 (will never fill the Model 12's large shoes but I like where the safety's at and it is a slick action. A scope is mounted on mine for use in hunting Ohio whitetails)
10) Mossberg Model 835 (typical Mossberg in that it's a lot of gun for the money and the safety is exactly where it should be- on the tang. Got rid of mine because I found the gun to be too light in weight when firing heavy loads- ergo, the BPS)
11) Benelli Nova (ugliest shotgun I ever owned but because it is reliable and has a very smooth action it stands duty as my hd shotgun. And the price was right)
12) Smith & Wesson Model 916 (the Hi-Point of shotguns except, unlike Hi-Points, the 916 was an utterly unreliable firearm. They didn't cost much but whatever you paid for it ,you paid too much)
