Gnome is just perfect for laptops and convertibles. I can quickly navigate it using the touchpad and super key. It also has better touch screen support, and with one extension (hide top bar), literally all of the screen real estate is available for your work. Hit the super key or 3-finger-swipe up and the UI appears. Do it again to show all your applications and desktops. Or just start typing to search. 3-finger-swipe sideways to switch to another virtual desktop. All my programs are full-screen and on their own desktop. The animations are so smooth, it’s a joy to use.
And the Gnome apps are just simple and reduced to what you actually need.
On a desktop PC I prefer Plasma for its customizability and smaller UI elements. It’s better for navigating with a mouse (although you can also turn it into a Gnome-clone or a tiling WM just with built-in options). And the KDE apps feel more “professional”, with lots of additional functionality, options and settings.
