100% fingers here!  I pick with my index, middle, and ring fingers as well as my thumb.  When I play chords, I like to pluck all the notes at once, or I'll play arpeggios.  I like slapping and popping ALOT, but since my playing is evolving more towards my fretless style, I've been slapping less these days.  
   
I don't like to compare a Bass to a Guitar.  A Bass is it's own instrument and requires it's own technique to play.  Also, I really enjoy the more physical interaction with the instrument demanded by using my fingers.  I like feeling that satisfying burn in my arms after a long practice or jam.  
   
As for getting a more defined sound, that's up to my fingernails, callouses, and technique.  All variables that can be tuned to get that perfect sound.

www.yesworld.com has the bass tracks (minus everything else but the taurus pedals) to Tempus Fugit and Siberian Khatru (which is also the name of my husky dog) under Chris' section, under transcriptions (there are transcriptions there as well - go figure).  It is really really cool to hear the man play, complete with buzzes, splats and some loosey-goosey eighths.  My favorite parts are the strummed chords and pick-muted harmonics in Siberian Khatru.  The only shortcoming is that it's not on an Alembic...
And Merry Christmas everyone!

fingers 50% slap 50% love to slap but   i love the feeling of my fingers on the strings i find it more personal also for more aggressive attack i play harder i beleive that you can make any noise with your fingers i love playing chords strummed with my nails dont like the sound of a pick i think it sounds artificial but that is just me everyone should play what they feel is best
