Ubuntu and Arch can't and should not be compared. Ubuntu is targetting the home user, and trying to make everything automated and also avoiding the cli (though you don't have to use the gui's.) Arch is for power users, or people looking to get their hands dirty learning the internals of a Linux system.
Seriously, what were you thinking? Arch and Ubuntu are totally different distro's with nothing in common except for the fact that they are using a Linux kernel... geez.. It even says this in the interview. Did you read it?
I don't mean to sound rude, so if I come off that way please excuse me.
That being said. I think Arch is a wonderful distro. I use it along side my Debian install and I really love it. I use it to play with all the new toys (gnome 2.10, kde 3.4 etc). It is still young, but it's chugging along smoothly, with a bright future ahead.
