The KDE 4 release series is nearly four years old. Yet many users still maintain that the KDE 3 series delivers a faster, more efficient, and more customizable desktop. However, their claims are rarely detailed, so the recent release of a new version of the Trinity Desktop Environment, the KDE 3 fork, seems a suitable time for an examination of the claim.
The last time I compared the two KDE versions, KDE 4 was still working out some of its rough spots, such as using Akonadi to manage personal information in a database. Similarly, although based on what was then eight year old technology, Trinity was still fine-tuning, adding such features as the ability to run KDE 4 applications.
Since then, however, both desktops have matured and added features. So how do they compare now in terms of speed, feature, and stability? It's time for a point-by-point look.
