I currently have Arch and Debian 13 Trixie with KDE Plasma on my main PC. I sacrificed EOS to free up that SSD and install Steam games there, freeing up space on the Arch and Debian 13 SSDs.
I didn’t replace Arch with EOS due to the current AUR issue, as I need some of the packages in there (such as the printer drivers and their cleaning utility). And even though they’re theoretically not affected by the problem, I preferred to leave Arch alone, since I’m not infected and everything is already configured.
On my old PC, which I used for a while when I had hardware problems with my main PC, which is an i7 3770K with an nVidia 980ti, I initially installed EOS with the AUR 580 drivers. But since I don’t use it often anymore and wanted to keep the latest nVidia drivers available for that card, I opted for Bazzite for this PC. I don’t usually use immutable and/or atomic distros—I don’t really like them—but I think it’s a good fit for this specific use case, while still wanting to stick with a desktop environment with KDE Plasma.
On my mini PC, with an Intel Alder Lake processor, I believe, and an Intel integrated graphics card, I installed Debian 13 Trixie, also with KDE Plasma, but with the LTS xanmod kernel (version 6.18), since I noticed it runs better that way. I opted for this option because this PC isn’t used often either.
In general, even though I’m not a power user, I’ve noticed that some of the software I use on Arch is either missing from many other distros and must be installed via flatpak or from source code, or has external dependencies that must then be installed from source code. Even if you install them, I don’t know why they aren’t detected correctly. Examples include Goverlay, GameScope, and so on. On Arch, you just install them, activate the service where needed, and that’s it, you don’t have to do anything else. On other platforms, however, this isn’t the case; you have more hassle with certain software. So I’ve mainly stuck with Arch/EOS, because it usually doesn’t require any further work, once I’ve installed the things I need.
