>Great documentation? Yes. Compared to BSD's, mediocre and subject to dramatic changes by nature.
I disagree, actually. (For clarity, I wrote this article, 9 months ago.) This year I have done short reviews of FreeBSD, OpenBSD and NetBSD. IMHO the docs for Arch are more helpful than any of theirs.
You could say *BSD documentation is more "comprehensive" but I usually find myself wading through an ocean to find what I'm looking for. On top of that, every time you try to look elsewhere, you just see RTFM. I can respect the sentiment, but having different variations of the same documentation can help understanding imo
