what is the difference between a large piston short stroke engine and a small piston large stroke engine?

For cylinders of the same displacement, what is the difference between a large piston short stroke engine and a small piston large stroke engine? This is a very important issue in the engine design stage, which is the ratio of the piston stroke to the piston diameter, also called the stroke-diameter ratio.
