Full agreement. I tried out Fedora and OpenSUSE, but the lack of documentation, lack of googlable answers and weird lack of some basic functionality drove me back to Debian every time.
Slackware is a notable exception: It has basically no up-to-date online documentation and googling your issues usually doesn’t help cause hardly anyone uses it.
But it ships with easy-to-understand text files that are usually right in the directory where you want to configure things, written by the main developer himself. And if you ask a question on linuxquestions.org, chances are you may get your answer from one of the dev team members.
