No, because the whole Manjaro concept is bullshit.
Delaying updates by two weeks for a few more checks could help catch some bugs that went unnoticed, but not in the way Manjaro does it. Which means with no rhyme or reason at all. They don't use the two weeks for additional tests. They don't even collect fixes or patches based on the bleeding edge experience of actual Arch to apply to their delayed updates. They just delay updates, fixes and everything by two weeks. So your system is exactly as unstable as Arch just with 2 weeks delay.
And it gets worse from there: Arch has a disclaimer about the AUR being unsupported and requires you to install AUR helpers manually, so you did it at least once the old-school way and actually see the disclaimer. Manjaro however gives you access to the AUR pre-installed. No, not a cloned version of the AUR that is also 2 weeks behind. Direct access to one as used by Arch that expects your system to be up-to-date, not 2 weeks behind... introducing a completely new kind of dependency hell and instability.
PS: And that's before questionable stuff on the Manjaro side... like letting their SSL certificates expire multiple times (and suggesting changing your devices clock as a "fix") or DDOS'ing the AUR with a bug in their AUR helper, also multiple times.
