Yeah I say who cares haha....I've had the pleasure of experiencing all three options at different times (had a jazz with an aguilar pre, have a jazz with an AC pre, and now have a passive KBP5) and when I had to choose it was always just a preference thing. Honestly, my favorite sound is just the passive KBP5. I think Jimmy really nailed that early CBS P-bass tone and it just translates unbelievably well from the wood and construction all the way through the electronics. His pre IMO, is really just a more powerful vintage passive sound so it's great to have live if you're still aiming for a more vintage tone like Paul does with Jamiroquai. The aguilar to me sounds way more like an active bass but I loved the bass control on it....super fat....but not as authentic jazz bass as the AC, so it makes sense Paul would slowly gravitate towards it.
Interesting to me that the boutique P models (Nordstrand, A-C) tend to be passive, while the J's tend to be active. I guess there really isn't much value in widening out the inherent tone of a P (versus a J). Hard to improve on the passive sound of a P with a preamp IMO.
....even when I'm in love with all my gear I still always find my way back to TB
