This'll probably heat up the auto vs. double war, and that's not really my intent, but if you're going to switch guns, I'd switch to a double. Yeah, you only get two shots, but you have a choice of chokes, the action is safe from dirt and water behind wood and steel, and feeding and extraction of shells is very reliable. I've only had rare jamb ups, back in the lead shot days, when the extractor would tear off the base of a paper shell, and you'd have to dig out the rest of the case with your pocket knife. I have seen doubles with ejectors that won't pop a swollen shell, but dropping a copper tube filled with lead will remove it, ditto for a stuck wad from a blooper shell. I suppose that'd work with an auto too, but the extractor is much bigger on a double.The barrels are easy to access when open, and less exposed to the elements when closed. You can shoot any kind of shell without any adjustment to the gun, I realize some autos do this too, but all doubles do it.
Part of my bias toward doubles is probably because I'm left handed, and most pumps and autos are designed for right handed use, but I've never seen an overwelming reason to give doubles up. Just so I don't sound like a snob, and can see some advantages to autos. Autos may be easier to load under certain conditions, you don't need room to swing the barrels open, especially vs. O/Us. You can also reload with a shell in the chamber, I'd like that. They're also supposed to reduce recoil, I'd like that too. They're also a longer gun, using the same barrel length, that extra length helps even out your swing, but I have short arms, and like the more compact double. I could see where a tall, or long armed person might like an auto better. The recoil is the same shot to shot, an O/U tends to climb higher on the top barrel, and a S/S tends to swing in or out with each barrel. I'll still stay with doubles though.
