Drupal has a reputation for being <i>the</i> tool for making community sites. Yet, I keep hearing Joomla fans insisting that Joomla is just as handy for communities. I'm used to Joomla, but I haven't used it for any community sites yet, so I have no measuring stick to start with.
SO: Which one do you use and why do you prefer it? Is Joomlaboards paired with Community Builder satisfactory or is SMF worth the extra effort? I'd love to hear your opinions.
