The last time I was meaningfully using Linux was around the time of Ubuntu 8.04 - my experience was the opposite of this.
When I have the time, I’ll be dipping back in on Zorin (which I think defaults to modded KDE) - I’ve spun up VM, and it seems like it’s worth a shot… I just need to confirm it’ll play the small handful of games I play, find a slicer app, and pull the trigger. Damn near everything else is Web-based or self-hosted.
