A flat top and less vibration go a long way in improving accuracy. I'd
say granite would be the superior surface if you are willing to take the
precautions, find other ways of using jigs and buy with a good fence to
start with.

If a lot of granite topped saws end up out in the market, there will be a
great need to secure jigs to the saw. Seems like an opportunity for
somebody. Perhaps a giant suction device similar to what the glass people
use to move those big panes of glass. In a pinch, you could use the Red
Green approach, good ole duct tape!
