you will get more movement between individual floor boards due to foot traffic and expansion and contraction than you will with large sheets, regardless of how they are screwed down. You will also get more thermal movement from a floorboard as it is a natural product with a grain running in one direction as opposed to aquapanel or ply. That means there will be a higher chance of the cracking and the adhesion failing. It may so you can on the packet, doesnt always mean it will give the best result.
