I wish someone who has done both would jump in and respond.
I clearly think we have the most in-depth and easy to follow process for learning. Some of their tapes, which are more general self-improvement, are entertaining, but do not necessarily adavnce one's information processing skills. There's nothing break-through in those tapes.
If they have a satisfaction guarantee, then order both programs. Keep the one you like best, return the other, and then tell us about your experiences here.
