Do you mean holosync?
You get virtual audio (makes the soundtracks 3 dimensional so the entrainment is smoother). Silent subliminals. The quality of the beats is superior. And I don't think that you can squeeze the carrier frequencies as close as they do on the 0.5 and 0.3 soundtracks (it requires sophisticated equipment to accomplish that).
That being said if you know what you are doing you can get incredible benefits from the bwgen. You can create dive-type soundtracks that drop you from an alpha brain wave state into a delta state (30 min) and then hold you there like the immersion soundtrack (30 min).
Bwgen is an incredibly versatile program but I don't think that most people get the most out of it because they just listen to presets rather then generating a long-term program that pushes their nervous system.
The presets seem to be more catered around accelerated learning states, generating lucid dreams or out of body experiences rather then long term growth and personal development. There are some knowledgeable users on the bwgen discussion board and if you can get some good advice and are willing to experiment you should have success with it.
