Love KDE. Can others share their experience of using the same desktop environment across distributions? Is there a difference? I have only used KDE on Fedora and it's great but getting the itch to try out something new. Void Linux maybe.

I run KDE on Void - both on my workstation and my ARM laptop. It runs perfectly on both. The only thing I've noticed that you'll 'lose' on Void is the 'Applications View' in System Monitor; that's only because it relies on systemd functionality that Void doesn't have because of runit.

I've tried KDE in Debian and NixOS, and the experience is exactly the same. In many ways the choice of distro is much less impactful than the choice of desktop environment.
