Well, the obvious question...why are they pushing Debian? It will be faster, you will learn more, however, as you can tell, many of us use RH.

If you have a completely working system, the performance is fine, learn all you can before you attempt a new distro. I believe that RH, Suse, MD are easier for the newbie to learn on, learn the concepts, and then, when ready, move to the power distro's like Gentoo, Debian, Slack. I could, but I like RH just fine, and a console is a console is a console where I do most of my work anyway.
