I've been meaning to finally upgrade from my ancient but perfectly functional Linux Mint 18.3 (based on Ubuntu 16.04) to Regolith Linux, with the intention of getting into an i3 environment.

Any thoughts or comments about Regolith?

EDIT to mention that for people interested in getting into tiling window managers (such as i3), the Pop_OS distro also comes with its own, optional tiling wm that can be switched on/off, which might be a nicer and more approachable middleground for newcomers
