I've been using Linux on the desktop for decades at this point. KDE Plasma is my current favorite and I've been using it for a few years now. It has everything you'd want in a desktop (maybe a bit more), looks great, and is very fast even on modest hardware.

My current job has me using MacOS on an M3 Pro Macbook and I find it barely tolerable compared to KDE. Usually when I want to do something new or change some configuration, either there is no way to do it, or it's hidden behind some key combination that I never would have guessed. I would describe the overall feel of MacOS as "syrupy." When using the mouse or typing, there is almost always some kind of barely-perceptible latency. Nothing is ever crisp and instant. (This isn't specific to this machine, it feels the same way on every Mac I've borrowed.) It's sort of like someone decided that the only way to make it smooth was to also make it slow.
