I don't know, I think they may actually work for many if not most styles - I'm finding this to be my go-to bass - with the P-pup & filter set low I can get an almost flatwound sound, middle filter settings give that split-coil P-pickup bark, both pups equal and filter set mid to high I can get anywhere from Jazz Bass to Ric to Alembic - IMHO of course! 
Oh for sure, my Ibanez is by far my most versatile bass. For about 16 years it was my ONLY bass, and I got by pretty well
Now though, I find that I usually play either my les Paul or my Greco thunderbird. Both of those have a distinctive resonant growl that I just can't get from the Ibanez, and that records exceptionally well for the kind of rock I'm playing these days.
And I love those basses' direct sound; but the activators direct to a board sound way too forward and too sterile to me without going through an amp and preferably miking a tweeterless cabinet.
But I'll never sell the Ibanez. It does things they can't touch... it's like my childhood home bass... and besides I've made it so weird looking that nobody but me would ever love it.
