A couple of years ago, I used both of them briefly and GNOME simply provided the more polished experience back then.
In time, I came to dislike the look/design of KDE apps.
So when the time came I wanted to ditch GNOME because I was sick of its extensions ecosystem, I didn’t even consider KDE Plasma. Instead, I tried out Sway and eventually settled on COSMIC.




While I absolutely adore everything
rpm-ostree/bootc, I do think operations involving it are relatively heavy; at least compared to what else is out there.Depending on your (in)tolerance, you might therefore consider opting for something else, instead. Assuming that this list does a considerable job at presenting your options, I’ll try to provide input on some of the more mainstream ones:
nixdoes handle operations more gracefully thanrpm-ostree/bootcon average, though.ostreeonly and thus doesn’t have the heavier operations fromrpm-ostree/bootc. The goals of the foundation behind it align with enabling low-end hardware. This is reflected in their system reqs. Note that GNOME is still relatively heavy, but you should be served well even on just 4 GB of RAM.bootcever since its Orchid release. So, it’s probably not that light. Furthermore, I got many questions regarding the health of its ecosystem. This used to be another serious contender, but I’m afraid it might have missed the boat…Having said all of that, the gist is basically that atomic distros are still relatively new. As such, I can only recommend Endless OS, Guix System and NixOS. Note that the latter two are rabbit holes, though.
