I ran opensuse for several years. It's not a bad distro, probably what
I'd still be using if I hadn't discovered ubuntu. If you have the time,
it's always good to learn more than one flavor of linux. Ubuntu is deb
based, suse is rpm based, so you'd get some good exposure to the other side.

Suse is a lot heavier than ubuntu and installs a whole lot more stuff by
default. Try it and see.
