I recommend ubuntu. It is pretty userfriendly and use the debian apt packet manager, which is superior to yast in my opinion. The install cd is also a live cd, which means you can see how it works before deciding to install it. For me it found and configured all my hardware correctly.
There are 2 flavors of ubuntu.. The one called ubuntu is a gnome centred distro while you have one called kubuntu which is centered around kde. They are identical with the exception of what window manager they mainly support.
