I own Hoff's version.
Its an ok translation. He bases his translation on that he self studied how to read CHinese and that the interpretations of some material by most people are wrong because in the era of when the TTC was written they did not supposedly speak and write like today.
Hoff also claims he is one of a handful translators who actually are practicing Taoists. Huge claim I think.
Lastly, in his notes on some chapters he has a tendancy to go on environmental social justice rampages. And many of his "facts" about the environment are flat out wrong and climate warming fear mongering.
