"The only thing with arch that is blocking a non-techy/fiddle-unfriendly person is the installation process "

I think your definition of "non-techy/fiddle-unfriendly" is quite different from the rest of the population.

Also note, that just because you happened to had months of no problems, that does not mean it will be the same experience for someone else. Speaking of it: for a non-techy person, using the terminal is already a problem.
