Moment of inertia is a measure of the resistance to angular acceleration. It equals the mass of a particle in an objected multiplied by the square of the particle's distance away from the axis of rotation, then added for all particles. Therefore, with objects of the same mass under the same forces, those which have particles with the closest average distance from the axis of rotation will accelerate faster.
Cool experiment!

Cool, mind explaining why some shapes work better than others?
