^^There have been a lot of threads on this subject. It all boils down to what you plan to do with the car and personal preference. If you plan to track the car (HPDEs) then get plain rotors.
If you drive the car on the street you can pick any rotor you want. Just make sure it will work with your rims/tire and brake calipers.
Cross-drilling and slots are just for bling, and really don't have any real function with modern braking systems.
Here is a link that might help.

The Track-specific Viper ACS and ultra-incredible performance Caparo both have slotted-only rotors. While I agree that drilled holes are bling. This is certainly NOT true of slots, as they were the ONLY way I could run the excellent OEM pads without getting the dreaded uneven pad deposits and resulting pulsating brake pedal syndrome.
In addition, instead of ending up with burnished and hardened pads after 5 years, my C5's pads are always like brand new - kinda like a pencil eraser that is shaved slightly before every use. It does a better job for obvious reasons.
Even the new Cadillac CTS-V, haulin quite a bit more weight than our C5s, comes with slotted-only rotors. GM finally got it right!

The super high end rotors are ceramic-big $$$$. Slotted rotors are "OK", cross drilled is probably useless in most cases, they are prone to cracking around the holes. I've seen some that are dimpled (the hole is not drilled through).

^^The real high end rotors are carbon. The big advantage of carbon is weight. The ability of iron and carbon to hold heat is about the same. However, when racing weight matters.

I always heard carbon rotors work better the hotter they get. You see them mostly on NASCAR and NHRA cars.
Very high $$$$$
your are right Inde, the drilled to crack under allot of heat. For regular street use they are just fine.
