I had to implement Wordpress for a few projects but everything other than simple blogs would become a little laborious to maintain. In my opinion there’s not much use in comparing Wordpress with other CMSs as each will have its strengths and weaknesses. In my perception Wordpress (as well as Movable Type) is strong as a blogging platform while other CMSs like Joomla, Drupal, CMS Made Simple, etc. are much more aimed at actual content management with everything that comes with it. These CMSs often also have blog modules/extensions to complement the basic software but these are not as strong as Wordpress.
In the end it’s the type of the project that decides which software is best.
