I started a few threads about this in the past. I own 3 800 series. I fitted new bone saddles for each one after buying them. Now, 2 years later, they all use Tusq and Micarta. It sounds better on these guitars. My $0.02 (total speculation) is that guitars that have excess bass (and less treble) to start with sound better with bone, which emphasizes the upper register. I think guitars that are balanced to start with sound better with Tusq or Micarta, which I consider to be more tone "transparent." I think a great deal has to do with the voicing. As a practical matter, Taylor prefers the consistency of Micarta (they seem to have a new formulation) with their ES2 pickup system. In terms of emphasizing the upper register: Bone>Tusq>Micarta.
