Kubuntu

Ubuntu is one of the simplest and most user friendly Linux distributions. It's based on Debian like many other distros whose roots date back to the distant 2004. Ubuntu is, by default, a GNOME (Unity) based environment which is OK. But my opinion is that Windows users will find it a little bit confusing. KDE is much better for them. Kubuntu is official flavor of the Ubuntu based on KDE plasma desktop, started in 2005. From the perspective of SQL Server there is no difference at all because most of our work will be console based.
