I also manage my own Ubuntu desktop for work, and had to reinstall the system 3 times from scratch because it magically stopped working. In the end it turned out to be something with a new kernel, but it took me, dunno, 2 days to debug.
My work-issued Macbook Pro regularly forgets which monitor (my external monitor or the built-in display) is the primary monitor and moves the dock and task bar between them seemingly at random.
My mouse sensitivity is cranked all the way up but my mouse still feels like it's mired in tar compared to my Windows and Linux machines.
The dock is always in the way. I can hide it when a window approaches/overlaps it, but it often takes multiple swipes with the mouse to get it to reappear. Completely removing the dock (which would be my preference) does not seem to be an option. I was able to move it to the left side of the screen, which is better - why take up so much valuable vertical screen real estate with a top bar and a dock on the bottom???
So... I don't know. I'm not seeing it personally. For me Gnome, KDE, Windows 10, and Windows all provide a better GUI desktop experience than macOS.
I set mine to around 40 seconds. I haven’t seen my dock a year or so.
Note I’ve not jumped to Monterey yet so this is untested there.
I think you need to increase the tracking speed in "Mouse" preferences. Mine is about 75% and I can move across a 1440px screen with just a small flick.
Oh sorry, might not have been very clear, thats what I meant.
As I say I haven't used MacOS in a while, but in my eyes its always been the strongest choice in terms of stability, with the tradeoff being control and to an extent (depending on what your doing with it) compatibility.
Windows seems to specialise in compatibility, Linux in control (I prefer saying that than customisation, which in my view makes light of it) and MacOS in stability.
It's the reason I didn't move to Linux at home when Mac laptops were getting so awful a few years ago.
Linux will let you shoot yourself in the foot. That is not a Linux problem, PEBKAC.
