I'm a little more inclined to think that what slotting does is do a better job of keeping the pad surface fresh and give stuff like brake dust, water, etc., some place to go initially.
Once you can reliably lock up the wheels, further brake torque is not really useable. But there can be differences during the transition from zero to maximum braking.
