The reality is for street use it doesn't matter. Use whatever you like. You shouldn't be using them hard enough to cause cracking issues. A common or garden variety plain disc is cheap and looks after the pads so would be best unless you want purtiness.
For track use it does matter and slotted rotors (done correctly) are what you want. Drilled are to be avoided. Solid rotors aren't as good as slotted. Slotted you need to ensure they are done right (so no slots to the edge of the rotor, proper radiused finishes etc). Then you get into hats, cooling vanes, material etc etc.
