I like the simplicity of passive circuitry, but a few years back I bought a Spector Euro LT that had a Darkglass circuit and the thing was alive compared to my passive kit, so I went to active route on everything else.
Updated John East/Darkglass circuits on all but two of my basses, the Spector Euro-X has (I think) an EMG circuit.
I just feel that a cut/boost active circuit just gives you more control over what hits the preamp; lows, mids, highs, bright and therefore an almost infinite level of control combinations. This obviously is all subjective; this isn't to say that great tone doesn't exist from a VVT potted bass, because it does.
Ultimately, use active circuits sparingly. It's not all about just having everything full on.
