Is TR Pro worth it?

I know, that question is like going to XYZ Linux Distro forum and asking if XYZ is a good distro, but I've been wondering.

It seems like, from what I can tell, the information in the downloads is all freely available, but it's more a matter of presentation and organization than the information itself.

Am I way off the mark here? I obviously can't know the quality of documentation until I get a pro membership, but I'm hoping to get an idea.
