5 Distro's in a Week

[LiamOS]

Give Bodhi Linux a spin sometime.

Also, if you liked Arch, definitely give Gentoo a go. It'll probably take more time to set up, but it's a real winner if you can get your head around what's going on.

I say try openSUSE out next, its both rock solid and asctually has a lot of packages in it as of 12.2

I have used servers with OpenSuse and they have some fairly back-level things (like the GNU utilities...).

Fedora -

A Red Hat breakoff, Fedora is a wonderful DE for someone who really wants to get the most out of Gnome. Fedora runs on the latest release of Gnome and it is nice and quick. I actually found it more responsive than Unity on my system. I would say however it is much more difficult to get additional drivers, codecs, and such as they do not come preloaded on Fedora, and you have to hunt them down as well as their packages.

Have you tried adding repos from here? --

Um... what? All distros have GNU utilities in the repos.

Of course, but not all at the same level. The Gnu coreutils on my Ubuntu 10.04 have a 2009 copyright, and those on the OpenSuse server at work bear a 2005 copyright (and these systems are fairly recent installs, planned to last a few years, so I doubt these used a very back-level version...).
