From the technical analysis point of view, Holosync follows the most basic setup - simple rain background and single binaural carrier below the hearing threshold, starting in alpha and ending up in delta (I could look up the exact frequencies, but you prolly don't need that). They claim that people achieve great results with their solution, but I have nothing to say in that regard - make your own conclusions.
What is so "advanced" about it - I don't know.
BWG is the most versatile tool, but every single preset that I tried is absolutely no good. If you plan to use it, prepare to make your own presets. You can try it for free - its shareware.
I use my own recording (BWG + MATLAB + several hours of sound editing). I've designed it to be EXACTLY like Hemi-Sync in terms of background, but used custom BWG-generated carrier tailored for deep trance - it takes the listener down from 10Hz to 2Hz (exponentially scheduled) over the course of one hour.
Contact me if you want to try it out.
