When I tried it a few months ago, I found that documentation was very sparse. It was difficult to even find out all of the things they had modified from either standard fedora or bazzite.

And while the reviewers complain of it being sluggish in a VM (not a good real world test IMHO), I too found it to be slower than a standard distro.

I like the ideas from uBlue, but they seem to have far too many projects to properly polish and support each one.
