Chakra GNU/Linux is a unique spin on Arch. Originally a KDEmod for Arch in 2006, it broke off in its own distro sometime in 2010. It is a pure QT distro meaning that no GTK based programs are available in the default repos. Following the KISS principle tightly it is straight to the point. Also following the half-rolling release model it updates with the latest (stable By default) versions. It also uses its own repos, the CCR. The only complaint most people have is the current lack of a gui package manager, making users rely on pacman. Although it is being worked on at the moment.
Conclusion: Chakra is a wonderful pure KDE distro, and probably even the best. Fun Fact: The article was written in Chakra.
