No it's really not. I've had enough problems with badly-maintained/broken packages that I've switched to Archlinux (btw). Just go with Debian Sid or Arch.
openSUSE is a great all-around distro, not only for sys-admins. It comes in two main flavors: Leap (stable) and Tumbleweed (rolling), and several others. The main difference between Tumbleweed and other rolling with other distros is the quality control before releases. This is done almost daily. If for some reason the quality check does not pass, the release is hold until it is solved.
