Short answer to you question is no.

I am currently using Arch. I have been using Linux for some years and I am going in a direction where I want to start out with less and add what I want. I have no doubt in a few years more I will be using LFS and doing it all myself. However I still have other favorites. Debian, Fedora (Red Hat,) Mageia (Mandriva, Which was Mandrake that combined with Conectiva, Mandrake and Conectiva forked from Red Hat,) Ubuntu/Xubuntu (Debian Based,) Mint(Ubuntu/Debian Based,) Suse (Which forked from SLS,) Sabayon (Gentoo based.) I plan on trying Slackware in the future, which also forked from SLS about the same time Suse did and I want to give Gentoo, (which was Enoch,) a try to. All are good, all are Linux. It depends on two things. What the user wants and how it is marketed to the public. Debian has always been Debian and is a great Distro but to say Debian based ones are better then other Distro's would be unfair and incorrect.
