I recently spent some time evaluating a bunch of different systems for migrating away from Ubuntu, including several Arch-based ones.

I was the most impressed with Manjaro, it seems very well polished. From Gnome 40 on Wayland, to the the default ZFS shell with custom Powerline prompt, to the GUI desktop layout switcher which even includes the tiling PoP Shell as an option.

The Manjaro team has done an excellent job at assembling a configuration that is simultaneously power-user-focused but also user-friendly.
