As someone who's used a Mac for work while juggling a variety of other systems on my personal devices, my biggest complaint is actually the constant need to realign muscle memory for basic keyboard operations.

Sure, I could find something that would give me more familiar bindings at the system level, but I'd then also have to (hope that it's even possible to) also deal with all of the downstream apps that then have to use different ones, because the globals in macOS have superseded whatever they'd be using on other systems.

It's like dealing with English grammar. Swap Cmd for Ctrl and Ctrl(?) for Alt, except when you're switching tabs or windows and it's the exact opposite, or when whatever operation you need is bound to Option for some reason.
