Yes, it was more or less "proven" (judged by professionals) and written why in a book I read in the library. I'll check it again and give you the title of it.

Edit: I'll go to the library tomorrow and take a photo of the main page and the page containing that info in the book. I am not certain at the moment, but it was a book that purely focused on Linux. I think it was written by "Monitor", but it may have been someone else. Anyhow, more info about it tomorrow. :)

As for Ubuntu being user-friendly, I meant that many that come from a different platform to Linux like to use it because it's Desktop is easier to understand than Fedora's for example.
