ZOMG let the distro wars begin . Nice article, it is interesting to see how they all compare together. I use Arch because it's rolling release and I setup what I want. I run into problems with this from time to time. Hell the Intel 2.10 driver broke my DPMS on my laptop and I couldn't close the lid without my system freaking out.
On a side note it would be interesting to see a comparison between x86 and x64 for some distros. See which one is faster and where.
