recommendations for lightweight window managers for an old netbook

Hi, I've got an old netbook from Samsung that has an old Intel Atom CPU (Intel Atom N455 1.66 GHz). I installed Arch on it and am now thinking of a suitable window manager. I tried Hyprland (kinda expecting it to not work really) whick didn't start at all. Before I had Debian with Gnome, which technically worked, but everything was extremely slow.

I've used Gnome for a long time, but I know that there are a lot of other window managers out there. I would like to have one that avoids graphical gimmickry in order to be fast. (I like some nice little graphical details, but only if it's still running buttery smooth).

If you have some tips that would be very nice!

EDIT: thank you for all the recommendations I'll try out a few!
