Re: What's the general consensus on active pickups?
At this point in time, I'd say there's no consensus. There are players who will prefer one or the other of passives and actives, and some who are fine with both. And there are hybrid systems of passive pickups with active circuitry, like the Duncan Blackouts preamp or the Godin HDR circuit.
Each pickup type has its strengths. Both types can sound great. At the end of the day, I think it all boils down to desired playing feel. Passives generally have a more organic/lively playing feel. They are also simpler in operation - no batteries, etc. Actives generally feel more compressed, but that can be an advantage if one wants more even output across notes. They are quieter than passives in terms of hum and are faster to swap if using the EMG-style 3-pin or 7-pin connector.
I prefer passives, but I must say that a bog standard EMG 81 in a Les Paul-type guitar into a JCM or DSL-style Marshall is a beautiful thing. Instead of the usual 85 in the neck, I'd pair that with a Duncan Blackouts neck pickup. Man, that pickup sounds good.
