I voted "No" purely based on my own experience.
I've tried a few multi scale basses now, and I've found the low B to be no better than a well made regular bass, I expect if you analysed the differences you'd see something, but for the most part, I was left feeling a bit meh.
I've also found the lower range of the bass tends to overpower the upper.
To quote a bass player I spoke with on the subject, who shall not be named, "my 6 string Dingwall was the best 3 string bass I've ever had".
EDIT, I forgot to add, I was impressed with how little adjustment was required to get used to it however. I've heard that a lot and didn't believe it till I tried one. Still not for me though...
