Not all distros are made equal, particularly if you're a KDE user. KDE has had something of a rough time over the last couple of years. The transition from version 3.5 to 4.x hasn't been easy, and over this period many distributions have decided to use either Gnome or stick with KDE 3.5 as their default desktop.
But we feel KDE 4 has now matured to a point where most KDE users can safely dump their old desktop and move on to the new one. There are very few stability issues, and most of the functionality found in 3.5 has been migrated to 4.3. The question is, which Linux distro provides the best experience for KDE users?
Rather than providing simple packages for KDE, a real KDE distro is likely to include GUI refinements, usability tweaks, custom themes, artwork and a good selection of KDE applications. It's also nice when Gnome and GTK applications play happily with their KDE counterparts, especially if a compatible theme has been chosen from them both. KDE-based distros should be able to do this better than simple Gnome desktops.
So, we took eight of the top KDE-focused distros and pitched them head-to-head to find which ones really rock, and which ones just limp along with a vanilla set of packages.
