Slots, holes or any other void in the surface of the rotor are NOT there for purposes of dissipating heat. Old-school race pads used to let off gas as they heated up which could form a bubble between the pad and rotor that contributed to fade. The holes/slots help remove this gas. But with modern street pads, even performance pads, the gas is pretty much a non-issue.
The nice thing about most drilled/slotted rotors is they have a coating on them so the hats and vents don't rust. I personally had ATE PremiumOne rotors on my Miata.
I had wheels that showed my brakes right through them so in addition to Hawk HP+ pads (noisy, dusty bastards they were), Goodridge stainless lines and synthetic fluid, I went for the rotors purely for looks. The pads and my sticky Hankook Z212 tires were what stopped the car, not the pretty rotors.
