Its all preference, and actives or passives can be used for anything. Its all in the user and how they're setup in the guitar. Thats my thoughts

actives give a little gain boost and a higher output. Theyre great for metal, or higher gain stuff
#5
IMO- passive's are beter for clean/60's/or classic rock stuff, and active's are better for hard rock metal, etc..... it's really just your opinion.
