Just realised that I’m well past 10 years using Manjaro.
And even more, my installation (xfce, stable branch) dates from Feb. 2017.
Using it on a daily basis for various purposes over the time (statistics with R, QGis, bit of sound manipulation with Audacity, etc.)
Bottom line: Continuous updates and various changes in setup and software since 2017 – It never failed me!
So, on this occasion a big THANK YOU to the developers and the community for keeping the show running for me !!
I have 3 more years to go until a decade. At the moment, I see no reason to change distro. This is one of the rare communities I actually participate in. 
Used Manjaro for years, almost always in unstable branch. Some annoyance now and than but nothing dramatic.
It must be about a decade for me as well on Manjaro. I did join the (old) Manjaro Forum shortly after getting it all set up to my liking and found it (Manjaro) to be a great experience once I got over the initial hurdles (not knowing so much about Arch-base back then).
As for the Forum, it has to be one of the best, in my experience.
Never looked back. 
(I do have a couple of Mint installs, but don’t often use them).
