I am not a sysadmin and very far from an expert so my take on this is entirely anecdotal and likely partially wrong.
But ever since I moved to Manjaro (after briefly trying Arch and deciding that I don't want to build my own house brick by brick) I've only had 1-2 problems ever and they were fixed literally the day after with the next system-wide update command. The one and only exception is the last problem I had: namely an OpenSSH upgrade hard-deprecated a few signing algorithms so I was unable to SSH into my servers. And that was solved with half a minute of search on ManjaroForum. Smooth sailing.
For all the BS surrounding the "systemd vs. whatever-else-the-other-thing-was", I found the former made my life as a mid-tier Linux user and home-grown server admin much easier, too.
