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 find cinnamon to strike a nice balance of speed and function if you have an ok processor, it’s straight to the point and doesn’t try to make you use summoning circle on your trackpad to do anything, like gnome does, but still has enough features and native configs to not make you feel like you’re missing anything.
