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?
Hyprland is my go to, but it requires a lot of effort compared to proper DEs. I really like KDE as long as you don’t ask too much of it. The UI is nice & it doesn’t use too much battery if you cut down on effects.
