I'm currently playing a four string fanned fret bass. I find that it does help balance tension/tone/whatever across the strings. I also find that my muscle memory is better; for whatever reason, I spend less time looking down at the neck. I also like medium scale basses, so that 32" G string suits me just fine.
Is it essential or a major "advantage?" Of course not. There are too many parallel-fret basses out there for that argument to hold water.
However, if you want a bass where every detail has been carefully visited and revisited, and where nothing less than perfect craftsmanship is acceptable, then get a Canadian Dingwall. I'll be able to comment on their Chinese line in a couple months, but I don't expect much less.
I still love my Spector and my P basses, though. Fanned frets are definitely not required for a great playing and sounding bass.
