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?
i3wm on my laptop, light on resources, keyboard-driven saves screen estate (no window decorations), and picom makes it easy on the eyes (rounded corners, shadows). If you prefer wayland, sway (and swayfx) is the way.
