The second Virtual Linux I tried was Fedora. Again, the gnome GUI is very reminiscent of Ubuntu, but there are some differences. I'm not going to go into much detail on this one as it lost my support during the installation.
I recently decided to test some different Linux distros on my work computer. I was going to do it at home, but my work computer is much faster and I don't care if I mess it up (did I say that?).
