For once I feel a little out of touch after I took a bit of a break from following the news to focus on studying, and suddenly everyone is talking about immutable distributions. What are they exactly? What are the benefits and the disadvantages of immutable systems?
TheLinuxExperiment has a good video about it: https://tilvids.com/w/3RjSzdS9jjK2y1nP3M6oJD
As far as use cases where immutable distros would be more or less convenient, it appears to me that due to the security and reproducibility factors, immutable distros are better for server or enterprise environments where updates need to be rolled out quickly and smoothly, which are most actual Linux systems out there and where Linux companies make their money (hence why they seem like the hot new thing right now), and for desktops where people are primarily concerned with not wanting to "break" anything. But a classical distro, IMO, would be better for folks like me who do want the control to change or customize things down to the core parts of the OS. As far as I'm aware, you don't have much freedom to tinker with an immutable distro until it's wiped away with the next update.
NixOS/Guix still give users the control to change anything at any time. That's because they aren't image based and instead they achieve immutability with the Nix package manager (symlinks and a declarative system configuration file).
I agree with immutable OS on servers being great, but I also believe immutable systems are a good choice for desktops. Especially managed desktops (eg. my moms) work well with an image-based OS. Flatpak is often enough for those few gui apps and there's less risk of automatic updates failing (eg. pulling power plug while updating).
I love Universal Blue.
It's OCI cloud image based Fedora Silverblue/Kinoite/Serica with extra steps/batteries included.
"The reliability of a Chromebook, but with the flexibility and power of a traditional Linux desktop."
But also probably an easier way for
Nvidia Fedorausers to game on Linux:- https://universal-blue.org/images/nvidia/
Easily roll back deployments or 📌 one and rebase to something else easy peasy. (So many different choices) Test betas with no fear!

I've actually been gaming on Bazzite for two weeks now:

Universal Blue isn't a distro. It's more of a reimplementation/enhancement of
ImmutableOCI Cloud Based Images of Fedora.uBlue is great. After using Fedora Silverblue for more than a year I used it to have the same OS on my laptop and desktop. It's works great and is quite simple if your already familiar with building containers. But the constant reboots and rebuilding an image taking minutes made me switch to NixOS.
The advantage of uBlue over NixOS is imo that the former is configured like any other Linux by placing files in the traditional file system hierarchy (e.g. binaries in /usr/local/bin). NixOS throws most of that over board and makes use of it's own configuration language and package manager. Getting started with uBlue is definitely easier, while NixOS is a time-consuming rabbit hole (not that uBlue isn't...). For a tiling wm setup I definitely think NixOS is the better choice, since changing core system components is quicker.
