That might be the case, but is there an alternative with a similar feature set?
The latest GNOME versions are even buggier, and when it does work, it feels like a toy project compared to KDE. It's baffling to me that it's been years since the v3 controversy, yet the project still doesn't feel as mature and polished as KDE Plasma.
All v2 forks also feel like someone's hobby project to bring disparate tools together, rather than a cohesive desktop. I'm sure some MATE and Cinnamon fans would disagree, but IMO the modern desktop experience has moved on since 2010.
Similarly with LXDE, Fluxbox and a myriad of others. These are great for certain environments, but none of them can compare to the polish that KDE has, let alone something like macOS.
To be fair, I'm not bashing on minimalistic or window manager-only setups. I've been using bspwm on Void Linux for many years now as my main working environment, and wouldn't change it for the world. But when I want to stop being productive, consume content, and not have to troubleshoot issues on my machine, I prefer to use a more featureful environment with a friendlier UI. Since macOS is out of the question, and Windows is purely for gaming (and even that is going away, thanks to Valve), KDE is pretty much my only choice on Linux. Which I've been enjoying for a few months now on NixOS.
But I do wonder if there is really a DE that can compare to it. AFAIK more ambitious projects like elementary OS, Deepin and Solus are still experimental, to the point where I don't even keep track of their updates.
