DistroWatch published a review on Hos OS 3.1.

The curious case of Hos OS 3.1

On the surface, Hos OS appears to be fairly normal. The distribution is based on Ubuntu. It ships with the Openbox window manager, the Chromium web browser, LibreOffice, and Snap support. The distribution is built for 64-bit (x86_64) machines exclusively and aims to provide convenient desktop features while running a lightweight window manager. Apart from the website's retro look and the project's pixel-art style icon, the distribution looks like a regular Ubuntu spin. At first.
