i use both, i like them equally, i have almost no use for linux, because all i do is play games, i use ubuntu
i have used in the past: ubuntu (GNOME), xubuntu x64, ubuntu 64 (GNOME), and im currently using kubuntu (KDE).....i dont like how there are so many different distrobutions for linux, i like that its free, but there arent as many programs for it...
i think windows is better because its more user friendly, there are more programs availible, except for the fact that its so expensive, i think windows is great
