bhenry,
I have tapes from both. I think Anna Wise's book is terrific. I'm not a fan of her tapes. She has a very flat voice.
I only have Brain Wave Suite from Thompson. They are wonderful tapes.
According to Alex, the alpha/theta tape in that set helps to approximate the Awakened Mind that is a particular brain wave pattern described in the Wise book: The High Performance Mind.
hope this helps 
Try checking out The Relaxation Company. They have very cool stuff.
