Corded will be 240 or 110 volts so the power factor (watts) is voltage x amps. They generally need to be designed to operate on a 13amp circuit, it's probably required that they list their wattage.
Battery models are perceived to be stronger the more powerful the battery but that's not taking into account the design of the motor, power use etc. It's easier to look at the speed and torque of the drill and decide if that works for the jobs you want to do, that applies to corded and cordless. It's a bit more complex assessing SDS drills.

When buying powertools, why is it that a corded model will be rated in Watts but a battery version will give you only the Voltage?
