For me the Gnome 2/3 split was when I felt Linux became unusable, but thankfully alternatives arose. Same for windows after 7. I have to use macOS daily, and still find it less ergonomic than my cinnamon desktop. In macOS there are areas where it’s meticulously designed to the smallest detail, and glaring holes where obvious easy wins haven’t been sought. There’s a lot of polished jank.

My biggest pet peeves in Linux desktop land are with the polish, not the behavior. But then again, I’ve standardized on 1080P across the board for years, so I’m not the kind of person too caught up in visual minutiae.
