I have started using Arch in 2016 and it was stable back then. Are you describing an earlier era?

That does sound significantly longer ago then 2016 ;)
This would be back in the 00s. I would guess that Arch got stable around 2010? I was using Slackware as my primary system by then so don't know exactly when it happened, someone else can probably fill in the details. I started using Arch when it was quite new, within the first year or two.
The switch to systemd is the last time I FUBARed my system. 2012 it looks like?? I simply did not even remotely understand what I was doing.
Not OP, but used Arch for a while in 2011, and at some point doing an update moved /bin to /usr/bin or something like that and gave me an unbootable system. This was massive inconvenience and it took me many hours to un-hose that system, and I switched to Ubuntu. The Ubuntu became terrible with snaps and other user hostile software, so I switched to PopOS, then I got frustrated with out of date software and Cosmic being incomplete, and am now on Arch with KDE.
Back then I used Arch because I thought it would be cool and it's what Linux wizards use. Now Arch has gotten older, I've gotten older, and now I'm using Arch again because I've become (more of a) Linux wizard.
