I recently distro hopped from Pop OS Cosmic to Fedora KDE Plasma; omg I love it. There are very small bugs, but i really like that they have a feature where you can self report them to fedora. But overall, everything about this distro is already running better on my laptop and not chewing up my battery, and it just works.
Fedora really outdid themselves with these customizations, like holy crap.
Yea I also just found about those recently. I never really gave KDE a chance because I think the default theme does not look good, but now I kinda think its by design and is only intended as baseline for it be customized similar on how HTML looks without CSS.
