Ubuntu does indeed rule. It's very user-friendly, and kicks SUSE 9.2's ass (that's my former OS). With the synaptic interface for apt-get it's easy to install a *lot* of stuff, and the "System" menu lets you setup virtually anything graphically. It looks really nice, and the desktop is very clean. Even the trash-bin is in your panel. The people at Canonical and the ubuntu community are very friendly, so that's another pro. I'm sticking with Ubuntu
edit: And the screensavers are cool!
It takes a while to browse through them all and select the ones you like, but then you get real cool screensavers. You can select some, and have these used randomly. SUSE 9.2 could only do random of *all* screensavers, which basically sucked
