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 usually prefer DE’s based on my needs.
KDE plasma - for customization and features.
GNOME - for UI and simplicity.
cinnamon - for windows like and simple.
