I've had both of these books and browsed through them. I liked Nimbus better but neither one's style appealed to me, although I've liked other books by EJ. I believe Nimbus is the earlier version of Creation Story Verbatim. Nimbus is the companion book to Secret Talks With Mr. G. Along with a video, these books featured EJ Gold in makeup imitating Gurdjieff. In Secret Talks Gold slyly planted subtle claims to being the true succesor to Gurdjieff through a "Second Foundation" and other claims. The Gurdjieff community had a very strong reaction to Gold's actions and older foundation people still dislike him. The English kept his books out of England for years with a very strong campaign against him. Sorry I don't have much to say about the content of the books. I remember Creation Story being more like one of his theater pieces and Nimbus was more in the fake Gurdjieff style.
