Atomic updates means updates either apply or don't: there's no partial/fail state that can stop your PC from working. And in the rare event that an update has issues, you can instantly boot the previous two images, without typing any commands or using any fancy restore tools. And if you're a bit tech savvy (ie you know how to type a single command), you can even go back upto the last 90 days worth of images (via github).
The best part of atomic updates is OS upgrades, they work flawlessly. In fact since updates are delivered as images, an OS upgrade is no different to any other regular update, unlike regular distros like Mint where you have to cross your fingers and hope that your system still works after a dist-upgrade (and I believe Mint's official stance was that they didn't support dist-upgrades, they recommend you to backup, format, clean-install and restore with every OS release. Not sure if that policy has changed now, but that used to be their stance for a very long time).
I personally installed Mint in 2014 and used the upgrade path until a month ago, when my distro finally started showing bad signs of being experimented on (by me, for 11 years) and it was easier to do a fresh install instead.

Like I said, I have been using Mint since 2014 and the upgrade was an official stance at least since then.
I think 3-5 years (let alone 10 years) is a long enough time to pass after which one should check before posting old information. Imagine someone talking about how few games Linux has (pre-Steam) or how impossible installation of Linux is (because one needs to order physical CDs).
Bazzite just works like I’d expect an iPhone update or a Nintendo switch update to work.
You'd also want stable, atomic, updates that can go from "one version of system software to the next" without breaking the system.
Recently, i had to reinstall my 7 year old arch install because a system upgrade after a year or so broke it... It's not like i can't sit down and fix what went wrong manually, it's just that i wouldn't want to ever worry about these things on my home theater/"gaming console" pc...
- Out-of-the-box support for Xbox, Wii, Switch, PS3, PS4, PS5, and numerous other controllers.
- Nvidia drivers and the latest Mesa for AMD & Intel pre-installed, with tweaks applied as needed
- Bazzite ships with support for additional Wi-Fi adapters, display standards like DisplayLink, and more
- Out of the box support for not only desktop PCs, but handhelds, tablets, and home theater PCs.
But the point is that, if you want to game on Linux, you probably want to perform exactly or almost exactly the same tweaks that Bazzite already does. So why bother doing them yourself?
It's not even a linux-from-scratch situation where you'd do it for the sake of learning. Googling "my controller doesn't work right", finding some discussion threads, and copy-pasting a bunch of fixes isn't particularly interesting.
