Rotors are heatsinks. Pads generate friction, which serves to convert kinetic energy into heat, which the rotors must absorb and dispose of. 'Good' rotors can operate at higher temperatures than 'bad' rotors without failing. Such temperatures are unattainable with street pads (maybe if you intentionally ride the brakes, but you'll definitely cook the pads). Yes, the rotors do serve as friction surface as well, but they're all made of essentially the same material. So the differentiating factor between friction surfaces comes down to how much of the pad contacts the rotor, where the undrilled and unslotted rotor is 'best'. Certainly, if you believe you may be suffering from pad out-gassing, you would benefit from slots or holes. I don't think you need be concerned with pad out-gassing at street-driving brake temperatures.
Saying that, I think any perceived difference in braking is placebo effect... unless there was something wrong/defective/broken with your previous rotors.
