When tightening a c'sunk bolt in (comparatively much weaker) plastic, the taper on the head acts like a wedge in the hole and can split out the plastic (a radial crack from the hole to the edge) if over-tightened.
You can certainly use c'sunk bolts; just don't over tighten them. I think they are much cleaner looking than raised heads.
