You can’t compare one of the most popular commercial forum programs with 7 years of development and thousands of ($$$) extensions to a fairly new open source project that’s not even a 1.0 release yet.

If you are running a small non-commercial forum, vbulletin is too much. If you are running a large forum that needs many powerful features, bbPress (currently) is too little.

Virtually all of the features you are asking for are possible on bbPress, with a bit of work and sweat. None of them are available without 3rd party plugins, some of which are not complete or bug-free.
