Why not download from the Pi's download page
the "Ubuntu Mate 15.10" image and try it out?
It's Ubuntu's ARMv7 Linux, plus Raspbian's Pi² ARMv7 kernel v4.1, plus some Raspbian Pi drivers (like Jamesh' nice hardware mouse cursor, I think. Full list is in this thread
). In my experience this ARMv7 Ubuntu runs somewhat faster than Raspbian on a Pi² when you use fat Linux applications like Libreoffice, Firefox, Thunderbird, etc.
Also, since Ubuntu is Debian based itself, you can use this Pi²-Ubuntu very much like Raspbian – just with very up-to-date applications. For example I use a SD-card with Raspbian and XFCE, and a SD-card with this Ubuntu and XFCE, and well, they are very, very similar to use. :-)
