Neither is Manjaro, but given the large number of updates that constantly “roll” through rolling release distros issue are bound to occur from time to time.
That is the reason for threads like these and the potential issues post at the top. Linux distros are a disparate collection of individually developed packages, melded into a cohesive operating system. Upstream bugs or integration issues … or user errors with pacnew files … will occur.
If you are not confident then wait a couple of days, read the update thread and get an understanding of possible issues and workarounds of other users.
Contrary to popular belief Manjaro is not suitable for complete Linux novices IMO … no rolling release distro is really. Linux greenhorns IMO should start with something like Mint, get to grips with Linux, and eventually migrate to distros like Manjaro if more current software and a rolling model interests them.
Now that Microborg has switched W10 to rolling release updates it has been causing a number of serious issues … at least with Linux you can switch to a more stable version release distro if you wish (ie Mint).
As for their market position, anti-competitive business practices over the last 25 years is the primary reason for market dominance … not their OS.
Linux is not Windoze.
