Ubuntu is for non-Linux users , for true hard core Fedora or openSUSE is preferred , after all the Father of Linux Linus Torvalds says he use Fedora or SuSE , so I go with the Master of the Linux Kernel and use one of those .
NOTE , after making the statement he only used Fedora (Red Hat) or SuSE , Linus was pushed and pestered by Ubuntu as to why he did not use it , he finally gave in and altered his statement , but originally he only stated Fedora , SuSE , seeing they were always a pure , advanced , and workable Linux . Originally Linus stated that Ubuntu was always in disarray , not good for a Linux Distro , and here is a thought , if Ubuntu is so easy and has so few problems , why is there a Forum filled with problems ? Ask yourself , just because a guy bought a ride into space , does that make him a Astronaut or just a Tourist with lots of money ?
Fedora or openSuse , for what it is worth , stay away from the U , teaches bad habits in Linux .
