I've been using Manjaro for like 7 years. Throughout these years I maybe had two issues with updates. I've easily fixed one by myself (it was a dependency issue), the other one was a bug in packaging. Mentioned it on their forum, they were crazy fast to reply (I wouldn't even expect that from a software company, let alone an open source project), and the fix was out in a few hours.
Btw their issue tracking related to updates is top-notch. This is another reason why I had a positive impression with this distro.
Regarding their own software, I am also impressed by their mhwd scripts. Even a shitty Nvidia driver can be easily installed with it, which actually works. And their OS installation framework has been adopted by other distros as well.
Okay, fair enough.
When I posted my original comment, I had the assumption that someone who uses Linux (or about to use Linux) knows at least the basic terms.
But to be honest, OP didn't even specify for what purpose they were looking for the worst distro. Maybe they meant for a docker image for their k8s cluster. Who knows. ๐คท๐ปโโ๏ธ
