Frontend Look, Feel, Usability (any glaring bugs?)

• Dolphin - Looks very good. However, there are so many bugs in this software. The forum only works in IE. You have to change code to get it to work in any of the other browsers as the forum is all XML! The TinyMCE editor is broken and always tries to send gzipped content. Many times, the editor does not show up on pages and you get a blank box. The broken TinyMCE instance also breaks administration of a few items on the backend. Huge setback for Dolphin, but should be easy enough for them to fix in future releases. We fixed it on our system so surely they can fix their product? A HUGE mistake on the part of Dolphin is including Social Bookmarks in places where they are not visible! We were 2 to 3 clicks into a profile or gallery component before there was a Share It link! Not only was the link buried, but many of the included bookmarklets did not work (shadows.com is a parked domain)! One plus for Dolphin is the Video Chat which none of the others seem to incorporate.
• phpFox - Easy to use with only a few glitches. Simple interface for everything and pretty much works for anything your users will want to do. We had a small problem with chat, but who uses that anyways? The look and feel is very simple with phpFox which is why it probably works. phpFox had the best events calendar of the bunch. It had a HUGE bug in version 1.5, but we used 1.6 for our test site and it performed well.
• Joomla - The 2nd best looking product out of the box, but can easily be made to be the best looking product with the templates available on the internet. Many people are designing templates for Joomla so a bad looking Joomla site is unacceptable. Stay away from too much Javascript, Ajax, etc as it may not function in everyone's browsers the way you think. Keep the technology simple when choosing a template and you will be fine. There are too many good looking Joomla templates that function without all the sliding this, and peel back that effects! The forum portion of Joomla is Fireboard which also integrates with Community Builder. It's a little clumsy at first, but with some tweaking is probably the best forum component of these players.
• Drupal - Very simple looking on the frontend. Even the paid templates were simple looking. Which is probably why Drupal just works! There has not been a lot of time spent on creating extravagant templates that don't work. Instead, get a "clean" template that works! Drupal and "clean" go hand in hand. The core Forum is not good enough to compete with the other products so Advance Forum must be installed. Drupal's user interface is not going to win any beauty contests, but will function very well and is intuitive to the frontend users. Drupal also does not have the TinyMCE editor many of your users will be used to using. Install it!
• Ning - Point and click for the users. The interface is the same on each and every Ning site so once a Ninger, always a Ninger. Just like the Microsoft File, Edit, ... menus. Easy upload of photos, videos, etc. The one drawback I have noticed with Ning is their users prefer to use backgrounds that render the sites unusable! You can't read the text once they put up these hideous backgrounds!
• Kickapps - Point and click for the users but not as easy as Ning. Easy upload of photos, videos, etc, but not as easy as Ning.
