I'd have to weigh in on the side of the Rem 870. I have 3 of them and I treasure them.
First owned was a 20ga, I was short and small so I had a gunsmith take an inch off the stock.
Sweet shooting machine. It was my primary weapon for years for everything from grouse to Slugs for whitetail deer.
Next one that came to my was a hand me down from a fishing partner. Originally owned by my Grandmothers Brother in law. Back in the early 50's when he bought it, I was 6 and he was in his 60's. We fished together for several years for up to a week at a time. When he died it was willed to me to be held for me till I was ready for it. Well it got misplaced someplace till I was in my mid 30's, its the older style with no vent rib, well worn, much loved in 16 ga. However better late than never. Thanks Orrin! Hows the fishin up there?
Last was a 12 gauge Trap model, 30 inch barrel, double bead, high rib, did dual duty as Trap gun and duck and goose gun for several years. I have burned many many hundreds of rounds through this gun. Both lower power 6's for trap and high power 3" steel duck and goose loads.
All 3 are dead simple to take down, clean, reassemble, rock solid dependable. Money well spent IMO.
