I was having this conundrum when A/B comparing my Ibanez Premium SR & a G&L L-2000.
The G&L gets there more "organically", with the flip of a switch or two.
The SR needs knob adjustments & turning the preamp on.
In the end I realized the most "organic" sound that I preferred was that of the SR with the switch in the passive position.
Shaping with a preamp can sound synthetic in comparison to the organic methods of changing up the wiring configuration.
One thing that I've decided on however is that I'm fine with boosting bass on the amp or the bass's onboard preamp, but I am not ok with boosting treble at the amp or bass.
You can still get grind & growl from the low end when it's boosted, but boosting treble just adds hiss & finger noise.
Glenn Fricker is all about cut vs. boost, for the same reason, added noise:
