Then it might be a matter of preferance or ability, because I can play lots tunes on the B3. However, I have ordered a Moog, and will report on my experience, and what I find to be the differance between the two.
Only thing is, I hate to spend that sort of money, only to have to play the instrument "backwards." That is, with the controls facing away from me; being left handed. I wrote a guy at Moog, and complained about how a short run of lefthanded theremins would not cost them that much! Hie sort of apologized, and told me how to rewire the thing, which is beyond my skill or desire.
