I think Gurdjiev is more popular in the US than he is in Russia. To the best of my knowledge, the flagships of Esotericism in Russia are Blavatskaya and Reurich. Unfortunately, I'm in no position to form my own opinion of Gurdjiev because I have no objective measures to evaluate his work. He had an interesting and productive life, for sure. And he probably wished for the good of the humanity. But other than that, I have no clue.
