I can't really answer your main question -- sorry. To say which had more "authentic" teachings, one would have to talk to someone who had seen both
the original, and the one in question, I suppose... or otherwise had some exposure to both...
To my understanding, there are also several orders claiming descent from the original Golden Dawn.
I don't know if the OTO or AA have modern branches.
The Temple Of Set gets into hermetic thought. As the name would imply, the ToS leans more toward the egyptian pantheon in some of their imagery, but
they really do study worldwide occultism (through a western slant, IMO). It may be fair to "warn" that the temple was created by Michael Aquino as a
tangential organization when Aquino left the Church of Satan. As such, certain elements of the temple have a "left hand" flavor, exploration of the
LHP is not discouraged, and some even accuse the inner priesthood of being "Setian" "satanists..."
