I use paperwm on Wayland gnome. If you like a scroll wm, is extremely easy to find out by installing the extension. It’s one click away. It might not be for everybody and has a few glitches, but fits my workflow better than other paradigms.
It tried out niri and found it identical to paperwm in most aspects. However, I like gnome and its features, so I missed those in niri. On the other hand niri didn’t bring me anything new. It is also difficult to install and configure and requires manual recompiling. I’ll certainly revisit it in a more advanced stage, should it reach such, but for now I’m perfectly fine with paperwm.
Manjaro is great.
