I'm primarily a Ubuntu user but I there are certain design elements of macOS that I appreciate. It's a common theme in reddit for users to post the desktop environments with a macOS skin and state no reason to use a mac now - but the workflow differences extend far beyond the look of an empty desktop with no windows open.

When working portably, macOS is my preferred OS.

I'm not sure about KDE, but Gnome's experience is severely degraded when outputting to an external monitor with different display scaling. Without Wayland there is horrendous screen tearing but pipewire isn't trivial to install which makes screen sharing while WFH problematic. Intel WiFi drivers are a hot mess. There are numerous other QoL differences.

While Gnome supports dynamic workspaces, the workflow is very keyboard based and without Wayland gestures aren't native (e.g. smooth scrolling between workspaces) - AFAIK the only solution is to emulate keyboard shortcuts which is quite jarring given a decade plus of having super responsive smartphones - but Wayland without pipewire is problematic for screensharing, etc ..
