That's a great advice! On the other hand, what is it that Arch offers and Debian does not? (Asking this as a long time Slackware fan.)
Newer packages? A rolling release?
What offer debian that arch doesn't offer?
Arch it is really stable and with latest packages. I see debian as a pain in the ass when you want a new packages or you have to upgrade to a new version. I don't have those issues in arch.
Better package management. More stability.
I think pacman is one of the best package managers. And as I said, arch it is quite stable, a little less than debian, which stops me from using it in production, but good enough to use it daily.
or Fedora
In 30 years the "you are using the wrong distribution" never gets old it seems.
Because it's still relevant, and there will never be a one-size-fits-all distro that satisfies everyone?
It works for the desktop OSes that actually matter and are worth selling software to, the fact that it is still relevant is the issue.
Or if you really don't want to have to deal with the overhead, choose macOS or Windows.
