phpbb 2.1.2 is a development version. It's not supposed to be used in a production environment. The snapshot I got comes out every hour, so the one I have installed is already outdated. The developers might break some features one hour and fix them the next. It's all in an attempt to see what they can and can't do.
Sure it has features missing that vB has, but it's not missing $160 worth of features. As for support, their forums are great. Even if I had a vB license, I wouldn't ever call their tech support line. Most problems can be fixed on one's own (or at least that's what I've found).
Oh, and the demo cp Unne linked to you is phpbb 2.0 (the current stable release of phpbb). phpbbhacks.com has prehacked versions of phpbb2, some with more features than vB. Of course I would never install a bloated forum.
