You're just reinforcing my point, not countering it. There's very little experiential difference, being superficial at best. But governing body and community differences are chasmic, meaning the Debian, Ubuntu and Fedora communities have little reason to add information for other distros to their guides; despite the instructions being 99% compatible.
Also visible in the popularity of the Arch Linux wiki as being reliable, up-to-date "how to fix it" instructions for common problems, regardless of whether you're actually running Arch.
