I've seen a lot of people who quite dislike Manjaro, and I'm not really sure why. I'm myself am not a Manjaro user, but I did use it for quite a while and enjoyed my experienced, as it felt almost ready out of the box. I'm not here to judge, just wanted to hear the opinion of the community on the matter. Thanks!
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Well even without that there have been several broken packages that would cause systems to be unbootable when installed. But yes sticking with just the major positories and flat packs would help. As well as taking your time on upgrades and letting other people test it out first. I may be a bit too old school these days. (Started using Linux in the early '90s) I hate snaps. Flat packs are okay but if I can get native binaries I'll generally go for them.
