Shortcuts are maddening when you just switch. But then you realise how much of the keyboard is underutilised in Windows. Linux uses the Meta key, but IIRC it was very app-specific, and not as comprehensively used.
A lot of MacOS is keyboard driven [1][2], but it takes up to two weeks to get comfortable (it took me at least that long when I switched to MacOS in 2008).
[1] But the new breed of "designers" at Apple no longer care about that. All new first-party apps that Apple vomits out are an abomination, UX-wise. And keyboard access there suffers as well.
[2] There are a bunch of shortcuts that will work the same way across most apps (such as Cmd+<comma> for settings, or text navigation shortcuts), and that is a blessing. You can also assign custom shortcuts to any menu item in any app if you need directly from settings. Or you can re-assign behaviour of Ctrl/Caps Lock/Alt from settings as well. There are small things like this all across the system, but it does take getting used to.
