What I mean is that using the terminal isn't mandatory in Manjaro while Arch and Arch based distros all require it. So for that it's an excellent example.
As for stability it's a bit more stable than Arch itself from my experience but I still has issues. The most stable distro I have used was Pop OS, I didn't have a single issue there for like 3 years straight, I only switched because of a hardware change and Pop OS's Mesa version was unstable on the new hardware.
My central point is still that you will never in a million years get the average computer user to use a terminal.
Yes, they can but an average user never will and for Linux to get any adoption beyond the enthusiast space it also can't be a requirement.
Like it's fine if you believe Linux should never get mass adoption and be a niche desktop OS. All I'm saying is that I want Linux to get mass adoption and for that terminal usage can't be a requirement because your average computer user, who's most advanced computer use is installing an ad blocker on their browser, will never open a terminal.
