We would need to see the video to see what the narrator is describing as needing "slight upgrades." Newer Ruger 10/22s come from the box with an extended magazine release, which is easier to manipulate than the old flat magazine release button Ruger used. Downside: the extended magazine release is easier to inadvertently trip if you're carrying the rifle out small-game hunting.
Ruger does still use a manual bolt-hold open that can require both hands to manipulate for some people. Not a deal-breaker in terms of pure functionality, just something that's a little fussy to learn. As mentioned, easily overcome with a file, Dremel or aftermarket parts. Or you can learn to live with it stock.
As far as the Ruger versus the Marlin 60, the 10/22 is a much more robust design from what I've seen come through my hands. It's very common to see well used Marlins with broken recoil buffers and other small parts. Rugers typically just need a good cleaning and maybe a new magazine, unless they have been subjected to VERY HIGH round counts. I've heard, but not witnessed, that it's possible for the stock steel bolt buffer to wear an elongated hole where it passes through the aluminum receiver, after enough firing cycles.
imashooter, 2-MOA at 50-yards IS just about an inch for group size. MOA doesn't mean a group is 1-inch, though people frequently declare a 1" 50 yard group "1 MOA". MOA is a geometric measurement; 1/4" at 25 yards, 1/2" at 50 yards, 1" at 100 yards, 2" at 200 yards, etc. And frankly a stock, non-target 10/22 that will reliably do 1" at 50-yards is a great shooting 10/22.
