I had the opposite experience with MacOS. I hold every OS I've used since the early aughts up against MacOS 9 and they are all lacking in terms of keyboard navigation. Maybe it was because I had the previous 10 years to practice, but I felt I could do almost anything in pre-OSX MacOS with the keyboard, only relying on the mouse for application-specific stuff like photo editing. Navigating, filtering, opening files and folders were all incredibly easy. In KDE it's pretty much a joke every time I have to save-as. Can't even get through that filesystem menu without a mouse unless it supports <ctrl>-l. Dolphin is slightly better, especially if you enable the console pane to make it easier to switch to the command line, but it's still way behind Apple's finder from 1999.
