bridgeposition, bright and with little hum.
Humbuckers tend to be less bright, so an active low impedance bridge pickup seems the best choice. Neckposition will work also, but may be a bit too bassy, and it depends on the guitar whether our “tone” knob can compensate that.
I name the hum here, because when you play softly (tapping with long notes sustaining), the frequencies colliding with the poweroutlet frequency (50 hz or 60hz) may interfere.

ps: I must add that some people just play with humbuckers, and that they are also satisfied with that… technically brighter pickups are a bit better for polyphony.
