youre going to get a bunch of varied responses. basically, what weve seem to conclude is that your skill level, board type (stiffness, camber profile), snow conditions and the amount of people on the slope will all affect what you want to do.
for me personally, i like to keep some pressure on one edge or another. there is merit to the argument that your board is faster when youre not pressuring an edge. where i ride, the snow conditions and the amount of people i need to maneuver around simply dont allow for it to be a safe option to be totally flat based.
