Arch is easier to use than Gentoo, LFS or Rawhide Fedora.
The Arch Wiki is pretty useful even for non-Arch users. Try to install Linux on some new or exotic hardware, Arch is very likely to be first at search results.
And it is elite, since it is more likely to be used by linux or OS developers (some way as fedora etc)..
Anyway, I think better way to learn Unix is FreeBSD (better documentation). And my main system is Ubuntu :-)
