Maybe I've gotten too used to it, but in terms of quality, OpenSUSE still does an excellent job. Installed OpenSUSE on a virtual machine a few days ago, and there it is, the perfect development environment. No problems so far, 11.2 worked out of the box.
Whoever came up with replacing crtl-c by "copy" in Ubuntu Terminal, for example? Disabling ctrl-c for a terminal user is just about the stupidest thing you can do (read: GUI users do not use a terminal anyway, if you're using one, you want to be able to abort a command from time to time with the standard command, not something catered to an audience of Windows converts)
OpenSUSE might want to market its former focus on quality more, if anything, and invest in delivering as consistent a user experience as possible. And some additional marketing wouldn't hurt Ubuntu didn't get its fame for naught. The only Linux distro ads I've ever seen on the Berlin U-Bahn (subway train) system were Ubuntu release ads.
