TL;DR: A step-by-step installation of Linux Mint on real hardware and setting it up for typical gaming tasks.
I don't really care much for SOG's other content but his forays into Linux over Windows were incredible for demystifying the operating system to a mainstream audience (i.e. people who watch his content).
Some nitpicks:
- Muta should have used the flatpak version of Steam instead of the system package, the Steam client updates itself (with its own runtime and all) so using a system package over just sharing with flathub is a bit wasteful (it does complicate external storage devices a bit since you have to manually set permissions via flatseal but that's it). (Edit: this is just a small nitpick, the native system package is fine as well).
- There should also have been mention of Bottles over installing Wine as a system package as well as things like the Heroic Games Launcher for GOG and Epic Games titles, Lutris is fine though.
- On long term stable release systems like Linux Mint or Debian, Flathub (or foreign package managers like Nix/Guix) should be your go to for installing software, let the distribution itself manage its core system components which I wish he clarified when he saw Flathub taking multiple GBs on first download.
Other than that, Linux stays winning. 
yeah pop shop is pretty trash at it, the ubuntu one was workable but not great last I checked (and ewww snaps), the options on arch are mostly pretty rough too...
I love the CLI but having a basic, reliable gui app for one of the most fundamental functions of the OS is worthwhile thing
Personally, things like Synaptic Package Manager hits a nice middle ground for me. I dislike stores (it always feels like I'm better off just going to the website) and I don't want to sort and filter rows of entries in the terminal.
wow, I haven't thought about synaptic in years! throwback! I did always find it a nice, functional option. If I hadn't made this shit a career and spent probably years of my life at a terminal, I might still be using it. It's literally better in almost every way than its successors, and its lightweight to boot... I guess that's what you get if you try to build an apt GUI, rather than try to make a flashy clone of the app store and just happen to use apt as the backend lol.
The problem I guess is that people need to learn how to use it. What even is a package? a repository? why does it say Amateur Radio? etc... But I don't think that's really a huge problem. Better to have functional stuff with a learning curve than intuitive stuff that's always broken and not very powerful.
Fun fact, the pop shop was forked from Elementary OS's "app center" because GNOME software was incredibly slow and unintuitive. Now they're replacing it with COSMIC store.
YaST and dnfdragora are reliable, though I don't envy anyone trying to teach it to a non-savvy induvidual.
I've never even delved into suse or fedora on a desktop lol. only on servers, and only a little bit (do not get me started on dnf in EL9. Impossible to use on a resource constrained system with any large repos like EPEL installed). They seem cool but I just don't have the time and energy to learn new distros very often anymore lol
