Ubuntu is a Debian-based distro. Debian is great, but if you're having problems with your Ubuntu installation, chances are, the same problems would arise.
If you wanted to sample other "finished product" distros, you could try your luck with OpenSuSE or Fedora. I suggest the latter, as there's a pretty huge following, considering that Fedora has Red Hat roots.
