Blood will Flow

Yes kind of - Angel passes get priority in all the queues for autographs and photo ops, and seats in the front half of the hall. You don't get to choose your seat like Creation, it is all done on the timings of receipt of emails as to where you end up - so some Angel pass seats are not much better than the front rows of Demon passes. But the queuing thing makes it worthwhile on its own.

One thing to bear in mind, JIB do allow transfers of passes until a certain date (at your own risk), so if you miss out on an Angel pass it is worth thinking about buying a demon pass then hoping you will be able to a) buy someone's Angel pass nearer the time and b) "sell" your own pass.
