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 EXWM with desktop-environment.el. It’s pretty bad for almost everything unless you reallyyyy like emacs keybinds.
However, if you just want everything in emacs, it pretty perfectly scratches that itch.
