I love that KDE is preinstalled. This makes it very easy for me to get my favorite desktop up and running in minutes.

Pros: 1. Kubuntu is an official flavour of Ubuntu but uses the KDE Plasma Desktop instead of the GNOME desktop environment. Some people like the simplicity of the KDE and and some find it unintuitive. 2. As it is part of the Ubuntu project, it uses the same underlying systems. It is robust. 3. Kubuntu shares the same repositories as Ubuntu and is released regularly on the same schedule as Ubuntu

Kubuntu is an Update version of ubuntu. Now it comes with a fantastic graphical user interface, tools and application as well. Kubuntu follows the KDE plasma instead of GNOME environment. This time it comes up with a wide variety of applications for the user interaction.
