I was wondering what others' experiences were with various CMS products. Which have you found to be the best? I realize the question is quite broad and the answer would usually be "it depends". But generally speaking my experience has been that Drupal is one of the simplest, cleanest, and fastest - whereas PHPNuke has been the one with the most features/power and appears to have the biggest following which lends itself to upgrades, features and plenty of documentation. Perhaps there are some good CMS out there that I haven't tried yet, so if you have any thoughts or a CMS product that has worked well for you please post.
