KDE

In Gnome (Wayland) you can 3-finger-swipe left or right to switch workspaces, up to show the overview with a global search and workspace overview, or down to show the top bar.
In overwiew, you can navigate between windows with the keyboard, close them with middle-click, and just start typing to open new ones with search.

With just 2 extensions, you can hide the top bar and every window's title bar, while still being able to quickly navigate between windows and workspaces. That way you use literally all the screen real estate on your small laptop monitor for what you're actually working on. The DE disappears unless you need it. It's so much smoother and faster than playing hunt-and-peck with the mouse cursor, which is a pain if you don't have a mouse attached.

IMO it's the best designed UI for portable notebooks, on any OS.
But on a desktop with a large screen, the UI elements are all way too big, and since you have a mouse in hand but no touchpad, it all stops making sense. That's why I much prefer KDE on desktop PCs.
