I started with pop!_os and their pop_shell on GNOME which also has tiling, and that's been fun :3..

At the moment pop is on the bench for me in terms of distro recommendations tho, cause of their work on COSMIC making it a bit behind, and possibly a bit unstable in the future

(Though COSMIC will be replacing TWMs for me, as it's imo a nice fresh spin on tiling with the window groups, which to me makes it the smoothest tiling experience even in the current alpha)
