I have tried out Gnome, KDE, Lxqt and Xfce on a regular desktop and all of them feel nice. I haven’t tried many DE’s on a laptop.
Are there any particular DE’s you like on a laptop, because of things like power consumption and efficiency that would not come normally into consideration for a desktop?
I’m using xfce everywhere, it’s simply the most lightweight and I got so used to fast reactivity that I couldn’t care less about barebone icons (and even those have come a long way since).
