AwesomeWM for me. I've essentially fused with it. Warts and all.

Does it not work on Wayland?

I can't imagine life without AwesomeWM.

Most stuff is fully rewritten/replaced. KDE and GNOME (maybe XFCE) are special cases. Sway acting as the Wayland version of i3wm is more what I expect. There was an early project to replicate AwesomeWM called WayCooler, but after a few years of trying to rewrite some major parts in Rust, the project died. There was a list of wlroots-based compositors at some point where most were replacements for the various old WMs.
