It's just Ford vs Chevy, with personal experience thrown in.
They're all okay. ...Regardless of my inflated opinion shared below.
Personally, I am a Marlin man.
I think the Winchesters are rattle traps, and the post-'64s feel cheaper than Turkish budget shotguns.
Marlins are easier to fit parts to, when worn or broken; but usually only need it because of abuse by previous owners. They don't disassemble themselves like Winchesters.
I own, or have owned Marlins from pre-war to 2018, including every decade except the '50s. After skipping the absolute worst of the Remington years (2009-2014), they're all fine.
Some of the years when Marlin had prolific quality issues were worse than the 2015+ Remlins. And some of the store-brand and 'alternate brand' 336-based models were built from parts rejected on the main assembly line. Some of those old Western Field, Kmart, Sears, and Glenfield "336s" were built by Marlin to an even lower standard than the vilified 'Remlins'.
I always thought they were "the same", just as you'll see parroted a million times on the internet and in every gun store. But they aren't. I learned that the hard way, by buying the cheap 'off brand' guns and parts. Marlin's "secondary" brands were normally built with the same parts as the flagship brand. But parts that didn't meet standards on the main line were also kicked over to the secondary brands and used there when possible.
I have one Glenfield, in particular, that is only ~4,500 units off from a Marlin of the same type; yet, it had a bad receiver, bad trigger plate, bad lever, and strangely machined locking bolt when I bought it. None of the parts fit any other 336 properly.
(Glenfield lever action receivers were not machined to lower standards than Marlin. They were, in fact, produced at the same time and in the same serial number sequence. Lots/blocks were pulled for Glenfield production, as needed, and stamped with the Glenfield 'G' on the side of the tang. But those rejected from the Marlin line were also kicked over for Glenfield production and got stamped with the 'G' by the hidden serial if they were usable.)
At least Winchester didn't do *that*.
As for my Marlins...
Some shoot pretty well.
Some shoot great.
Two, in particular, are amazing.
The only one that shoots poorly was amazing until a dirty, lying, scheming "gunsmith" butchered the barrel.
