According to my engineering text under square engines have greater thermal efficiency (less combustion chamber area, more thermal efficiency). Of course they then have higher piston speeds and more piston travel meaning more friction. Over square engines have the opposite problem, less stroke, less friction, but more chamber area, so less thermal efficiency. Seems like over time a happy medium has been found at square.
