Cross-Drilled or Slotted
For street applications, the stock ones are as good as you'll ever need. Drilled rotors are supposed to vent off heat better, but reduced mass means they reach heat soak faster, and they're known to crack. Slotted rotors are supposed to vent off gas that gets trapped between the rotor and pad, but if this isn't a problem, then you're just reducing surface area and mass.
