I've never liked the idea of drilled rotors for most street cars, though I know you will find them on some high-performance and racing cars to increase air flow and help keep them cool. That picture is obviously a humorous extreme, but, keep in mind that, whether on the street or on the track, the more holes you drill through a rotor, and the larger each hole is, the less rotor surface you have left rubbing on the pads for friction, and the less your total braking action will be.

2. Grooved rotor. The grooves give more bite and thus more friction as they pass between the brake pads They also allow gas to vent from between the pads and the rotor. 3. Grooved, drilled rotor. The drilled holes again give more bite, but also allow air currents (eddies) to blow through the brake disc to assist cooling and ventilating gas.

i read this about cross drilled and slotted rotors, see if you agree:
