For grannies, I like to go with Endless OS. Curiously, it combines aspects of the two most named distros under this post; based on Debian and utilizing OSTree (like Fedora Atomic does).

It's often overlooked (for some reason), but actually combines the best of both worlds:

• Over two years of support (since release), while Fedora Atomic only offers 13 months of support since release
• Automatic updates are enabled by default and updates are applied atomically in the background, while Debian(-based) are not capable of atomic updates
• Does not even offer installing software through apt and doesn't even have it's own rpm-ostree counterpart. Instead, it goes all-in on Flatpak.

The only thing that might give something like Fedora Atomic an edge would be by installing any of the opinionated uBlue images (like Aurora/Bazzite/Bluefin etc.) that just apply and ship fixes for you (without requiring you to do anything for it) and that are even capable of automatically applying updates to major releases for you in the background. This is basically just hands-off mode.

So you're saying that most directories in /usr and (also) some other directories in / are not read-only during runtime (under regular system maintenance/management) on Fedora Atomic?

I just wanted to offer some nuance to the table. After everything has been learned, enabling some (otherwise complex and obscure) features can be accomplished by a single line in your NixOS config. Like, this efficiency can not and should not be ignored.

You can find some of my thoughts on Fedora Atomic in another comment found under this post. Spoiler alert; for a lot of people, it's what they seek from NixOS but (by contrast) with excellent delivery. I won't ignore that it doesn't have some of the more insane/interesting functionalities that NixOS provides. But, some just want atomicity, reproducibility and (some) declarativity; and Fedora Atomic does deliver on those without requiring you to go into the deep and learn an entire new language that's only used for managing your distro 😅.

is PopOS! still the popular choice for desktop gaming?

Pop!_OS was pretty good for two reasons:

• System76 sells devices installed with it. Thus, onboarding (potentially new) users is something they put significant efforts into. As a result, it was a pretty polished experience that offers some unique functionality like factory reset and
• Easiest install for proprietary Nvidia drivers on the market

But, the Linux landscape is always on the move. And while the engineers behind Pop!_OS have put their hearts and souls into COSMIC (a new Desktop Environment), the current available version of Pop!_OS has seen only relatively timid changes. Thus, it has become less competitive over time.

For example, over the past two years, distros have erupted that come with built-in Nvidia drivers (pre-installed).

So, Pop!_OS has gone slightly out of favor. But, if you liked what you had back then, then it's still perfectly reasonable to continue using it.

But..., if you're actually interested in the latest and greatest Linux for desktop gaming, then we'd have to mention the following:

• Bazzite; built-on technologies made possible through Fedora Atomic. This is one of the few distros that, based on its installer, come with built-in Nvidia drivers pre-installed. Rock-solid atomic system that comes with all the bells and whistles without sacrificing any general functionality nor high security standards. Offers decent documentation (please consider to read up on it) and has thought up great onboarding solutions. All-in-all, it's (probably) the most hands-off gaming experience on Linux.
• ChimeraOS; this is more of a couch-gaming/console experience. Unfortunately, only supports AMD. Definitely worth mentioning still.

Honorable mentions:

• Nobara; Glorious Eggroll's (will be abbreviated to GE) distro. GE is well known for providing all kinds of gaming related goodies. For example, a popular set of Proton releases/derivatives is Proton-GE and it's often recommended over the others. So, the community was very excited when GE announced (and shortly after) released its contribution to Linux distros for gaming; a Fedora-based distro called Nobara. It did a lot of good things and still does. However, as a former Nobara user, I have to say that updates for major releases are pretty hit or (mostly) miss. This is not GE's fault; it's the nature of the beast. Reproducible distros (like Bazzite) are able to circumvent these issues with help of incredible engineering that goes on in the background. But, this is not Nobara's stronghold. (And let's not even talk about the bus factor.) If you're fine with potentially reinstalling every once in a while, then, by all means proceed. But, if you'd rather not, then other options are better.
• Linux Mint (Edge ISO); this is just the goodness we've come to appreciate from Linux Mint but with a more up-to-date kernel. Kernel updates often come with improvements to performance. So, with this, you won't be missing out. Like Pop!_OS, it's based on Ubuntu. The only caveat with Mint is the fact that it's not enabled to game from the get-go. The required steps to get it all setup aren't very hard, but it's great to just have everything setup for gaming from the start.

I agree that Fedora Atomic, especially if you consume it through uBlue, provides (somehow) even less headache with only a fraction of the investment.

I say this as a very happy user of Fedora Atomic; who has (almost) exclusively been using Fedora Atomic on all of their systems (read: 1 laptop) for over two years.

I would argue that NixOS absolutely is the OS you get if your time is worthless

Hard disagree. Does it require you to climb through heaps of trash documentation? Absolutely. But, if you persevere, you got yourself a rock solid system that will even make Debian Stable jealous; all while requiring no maintenance.

1. Better documentation has been made available since relatively recently.

Why does your brother use NixOS in the first place?

Don't get me wrong; I think NixOS is a very interesting project with a very bright future. It probably wouldn't be an exaggeration if I said that NixOS has single-handedly inspired the current immutable revolution. However, it's also a distro that wants you to learn and digest its ways before it will return the favor.

But, based on my reading/understanding of your comment, your brother doesn't strike me as a seasoned Linux user. Am I right? Btw, NixOS is hard unbeknownst of how many experiences you got with other distros. However, I would simply never recommend a new user to use (Gentoo, Guix System or) NixOS. There are definitely outliers, but they would have to find it themselves then.

Furthermore, a CLI instruction is DE-agnostic. So you don't need to cover the same topic with explanations for at least 3/4 desktop environments. GUI instructions also change a lot faster than their CLI counterparts; so by providing the commands one provides the method with the best longevity. Overall, it's just so much more efficient.

The main difference at this point isn’t what you can do with them, but how they’re set up by default

Excellently distilled most of my post.

I wonder if distros are interested to further blur the lines themselves; like how Debian and Fedora both enable Flatpak by default.

To be honest, I think the homogenization is a net positive.

Definitely. But I feel like we fail at capitalizing on this. Though, in all fairness, the fact that derivatives have lost (some of) their significance does convey to me that we're currently in a major shift. I just wonder where we'll end up and if there's anything we (as a community) can do in order to accelerate the process.

Thank you for touching upon the human-side of things! I wonder if my original point could be distilled to "Can we, humans, simply act more rational?" 😅.

Devils advocate - you might be getting extra layer of testing, by the “derived” distro testing community.

This is a good point. But, one might argue, that the problem itself is artificially created.

I do think that the very popular derivatives, that provide very sane and highly opinionated configs, have for a pretty long time been necessary for onboarding. Like, we can't ignore how important something like Linux Mint has been for this as an example.

And, regardless for how we move forward, we will definitely need distros like Linux Mint. But, I do wonder if it's worth for distros like Arch, Debian and Fedora etc to explore a beginner-friendly flavor/spin/variant.

The philosophies behind the different distros is definitely something I didn't touch upon earlier. Thank you for mentioning that!

I wonder how different the philosophies are between Arch, Debian Sid, Fedora Rawhide and openSUSE Tumbleweed.
