Sorry...couldn't resist!
Anyway, I've got a theory, so let me know if you agree or have a different opinion.
Active is for those seeking the comfort of their own home while sipping an expensive, boutique soft-drink (or single-malt - though I don't drink) on ice made (not if you drink single-malt, though) from finely, multiply purified water. Passive is for those who don't get that 24 frets and 9 strings can still be considered a bass (though guitarists might disagree, since they're becoming obsolete).
So...what are your thoughts? Active or passive?
I disagree. Active is for people who prefer having an on board EQ with all the tonal variation it brings. Sometimes they use it to get super hi-fi sounds, sometimes not.
Passive is for people who prefer the relative simplicity of the traditional tone and volume setup. Sometimes they prefer to have basically one single sound ("that sound!") they use for everything, other times they find that even a passive electronics setup delivers all the variation they need.
It has nothing to do with preferences for number of strings or frets. I might like a 21-24 fret bass, though it is not essential to my playing.
Similarly, though I use passive basses, generally I set up the pickups and tone/volume controls so that I have not one, but two sounds. 1: A really aggressive, bright, in your face tone for cutting through thick mixes and loud guitars and 2: A more mellow, subtle tone for use when the first tone would not fit well into the sound, quieter and less "bulldozer bass" and more "comforting pillow/teddy bear bass."
I don't begrudge other players their active, 9 string, 26 fret basses, but a passive two pickup 4 string, 20 fretter (though I'd prefer 21) I have found fits what I'm trying to do perfectly.
For what the bassist of Unexpect does, my basses would not be the best tools for the job. But that's why they make so many different kinds of basses, isn't it? If one kind of bass was the absolute best for everyone, there would be no need for all the others. People are very different from each other. It's not surprising that the instruments that they use to make music are as well.
Also, I like micro-brew beers.
