That’s almost a theological question ....I have used Remington shotguns since the about 1960 and have never had a problem. In fact the first shotgun I bought for myself was a Remington 870, and I use it to this day.

The Remington is a better made shotgun but both will last several lifetimes with reasonable care. I've never been a fan of Mossbergs but I know they work well enough.
I would suggest looking around for a Japanese made browning A-5. No longer in production but plenty are still around. Its heavier, but I like the elevated barrel (humpback) for aiming. I don't think the A-5 has been militarized as much as the 870 has tho.
