Clearaudio Master Reference vs. Basis Debut V ??

Need purchase advice on which of these two to go with. Am intrigued, yet concerned with the tangential arms on the Clearaudio- the TQ-1 2000 arm is $3k ; the Master TQ-1 arm is newer, bigger and stupid expensive @ $6k. Is this new arm magic or nonsense ? Would use Graham 2.2 on Basis, which would, btw, be the vacuum model. The Graham arm seems to be almost universally praised, while getting a consensus opinion on the Souther tangential arms is far more difficult. Any 1st hand advice would be greatly appreciated.
