I'm surprised you feel that way. I fight with my mac every day for one reason or another. At least it's not as bad as the days where some software used Cmd + letter and some used ctrl +letter, but for instance Cmd tab will switch to the wrong window when I go back and I have to use the mouse. Window switching in general is a lot harder if you only have the keyboard because the laptop is docked without a magic trackpad

Really? I find that on MacOS apps are very inconsistent about whether popping open a menu shows me hints for selecting items in that menu. Those same apps are consistent about it on Linux.

And then there's the bonkers window manager which can't move focus directionally (e.g. Super + left) and so you have to fall back to Cmd + tab tab tab tab but even then there's no consistency about whether you're switching between app instances or windows instances within the same app...

“Flawless” is absolutely the opposite of how I’d describe the third class keyboard navigation in MacOS.

It’s actually more intuitive to use a magic keyboard on the iPad than on the desktop OS.

Specific applications sure, but the base OS interface is unusable without a trackpad.
