I think part of it was the desire factor - when I found the '68 back in 2008 or so, I was into the history of Alembic, Phil Lesh, Darkstars, etc., so I was really excited and fell in love with the bass right away. I sold it mainly because I wasn't playing it and needed money, not because I didn't like it. Well, I had an issue with the E string - I tended to hit the string too hard so that it would hit the pole piece and make some mechanical noise through the pickup - pickup was as low as it would go without shorting out.
I have to admit I am skeptical about these new bi-sonics - but there has been so much hype about Darkstars, Bi-Sonics, on and on and on. The build quality of the bass was good, it felt good physically to play. A lot of my reaction is probably because of where I am coming from - I've gotten my Starfire fix, I wasn't excited to play this one. Someone who is really wanting the Starfire vibe may very well be happy with it.
