A while back I wrote Comparison of Operating Systems, but it turned into more of a tutorial than anything. It only compared Windows and Ubuntu Linux, my current OS. So now I am going to compare Fedora 15, Opensuse 11.4, and Ubuntu 11.4. Let's start with Fedora.
Fedora is a free Linux OS sponsored by Red Hat, the creators of Red Hat enterprise Linux. The fifteenth release (the most recent at the time of writing) includes the Gnome 3 desktop environment in it's fullest form. It has some Gnome features that you can't get from the unstable repository currently available on Ubuntu. It starts off with just a close button, but that can be easily fixed using the Gnome tweak tool. As an Operating System it didn't seem to vary much than how Ubuntu acted when I had Gnome 3 on it. It did have one serious graphical issue. I was doing some 3D graphics at the time using Google Sketchup 8 through Wine and it wouldn't boot in fedora. I did some Googling and sifting through the forums and found that Fedora had some unofficial Nvidia drivers instead of the ones found through Administration>Additional Drivers in Ubuntu. After manually installing these drivers all hell broke loose on the Operating System. It simply wouldn't boot after installing the drivers. This is a known problem and it wasn't something that I had messed up installing them. If you do 3D art or anything else that requires good graphics (Heavy desktop effects, gaming, and 3D just to name a few) then Fedora isn't for any Nvidia user. Otherwise it was a very nice and friendly operating system.
Arch can be seen as a canvas where the artist can paint whatever they wish.
Even though Ubuntu, Fedora, and Opensuse are great Operating Systems I have to make Arch the winner of this comparison. Arch just gives you the very basics and lets you decide what part of an Operating System you need. Do I use arch? No. Do I think it is a great idea of a Linux enthusiast to use Arch? Yes.
