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 use Gnome on my Thinkpad. That machine has an i7 and 16gb of ram. Ok my tiny Chromebook I got Mate. Very lightweight and almost as many features as Gnome.
