Would these 3 motors perform differently?
The #3 motor having ball bearings will outlast the sleeve bearings. A ball bearing motor can be run closer to 115% of FLA (full load amps) with creating as much heat. The larger Frame usually provides more torque at the same amperage. Small motors like this are usually rated in peak horsepower / 746W of consumed power is called 1 horsepower. This calculation is usually at close to locked rotor so no true power is being generated, just consumed. To answer your question You might find the larger ball bearing motor has 20-50% more torque at 746W so it would be much more powerful than the other 2 motors.
