We do need a comparison of these modules:
http://drupal.org/project/workflow - 12168 sites reported using & 136 open bugs
http://drupal.org/project/workbench - 10790 sites reported using & 5 open bugs
http://drupal.org/project/Revisioning - 7065 sites reported using & 34 open bugs
http://drupal.org/project/maestro - 440 sites reported using & 35 open bugs

Folks need to have a feature comparison.
