Customizations, especially theming, at the system level. Or just learning to modify system files on an atomic distro, in general. I’m sure it’s doable and I am genuinely interested in moving to atomic/immutable distros. But more for the security aspect than reliability as I’ve yet to break my install of Linux in a way that takes more than an hour to recover from. I’ve enjoyed the predictability of Debian and my very particular taste in UI makes for additional baggage just reinstalling, let alone moving to a very different distro.
In my experience, KDE can run just fine, but it is seemingly pickier about drivers and hardware (I’ve had a loose DisplayPort connection crash it several times) than other desktop environments.
