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 I don't use the snap or flatpak of anything ever i s2g it always breaks shit
snaps are annoying and semi-proprietary bs. Flatpaks are neat and useful, but the permissions model really needs work. Little shit often breaks with it it seems and flatpaks rarely receive the sort of attention a distro package maintainer would provide, even though it should require less work than maintaining a traditional package. I run so many apps that are predominantly distributed as flatpak, and yet the devs don't take flatpak packaging issues and little quality of life annoyances seriously (presumably because they run the software built from source in their dev environment and so never experience the flatpak)
Yeah. Snaps and Flatpaks are on different levels of annoying. Snap must die, there is no possible path to making it good. Flatpak is so close to good, the main problem is basically just that there are those little issues that I can't get over.
the fact that I can't drag and drop files into signal to send them? awful. I have to use a file picker, like a neanderthal
I do use the clipboard a lot for images though, at least that works
Exhausting to just have random core features never work and the only solution is to import a PPA or build from source by yourself
I like the AUR for that sort of thing but I guess that's not that much better than a PPA. Plus Arch are being massive dickbags and saying "we're x86 only" and deleting arm packages from the AUR so that kinda ruined it for me.
