Ubuntu is awesome, I'm a big fan of it, but I quit it because I really dislike command line. I used the 32 and 64 bit versions and both worked out pretty well, the 32 bit was a bit easier for those of us that like gui more. Kubuntu is next on my list to try out, it's supposed to be a bit more Gui friendly than the Gnome environment that Ubuntu is built on (Kubuntu uses the KDE instead of Gnome) Ubuntu is pretty easy for a beginner, I also tried using Suse, but in the end I liked Ubuntu more. In the end though, Ubuntu and Kubuntu are the same distro.
