It depends on how you are defining the word 'soft'. Quartzite is the hardest and most durable of the three - no question there. Shale can be crumbled with the tap of a hammer. Some loosely cemented sandstone can be crumbled when squeezed hard enough with your hand and some is well cemented and quite hard.
