Cross-drilled and slotted rotors give the maximum braking performance under all necessary driving conditions. Precision machined holes or slots on the rotors will allow hot gases from brake pads to escape quickly to prevent skidding or locking up. The quick response from pads to rotors will allow for improvement in stopping power.
Drilled rotors are prone to cracking, not always big cracks but micro cracks around the holes that can spiderweb over a period of time. Your best bet is either slotted rotors or quality blanks such as Brembo. Whats your price range? The slotted rotors wil disperse gas and will hold up well over time.

Brake rotors come in a number of flavors. You often see them vented, drilled, or slotted. Sometimes there's a combination of the three, and it's best to know which works most efficiently for the driving you plan to do. We know one of the biggest enemies of brake performance is heat, so the goal for any of these choices should be cooling your brakes to keep them from fading.

Jason Fenske from Engineering Explained is here to help you decide what kind of brake rotors you should choose.

Most brakes are of the vented variety. These vents help move heat along and keep your brakes in the proper temperature range they prefer to mitigate fading.

Slotted rotors are superior to blank rotors in some ways. Slotted rotor grooves offer two distinct benefits under heavy braking: brake fade, from high-temperature brake pad outgassing, can be significantly reduced, allowing gases to escape through the slots; and the grooves shave off thin layers of brake pad material, reducing glazing and improving braking consistency.

Alternatively, you might see drilled rotors on some high-end sports cars. You won't see these rotors on race cars though, as the drilled rotors can become stressed and damaged during the high-stress environment of racing. The reason you see drilled rotors on some sports cars? Honestly, it's because people think they look cool.

Slotted rotors are better for actual heavy-duty performance applications. They're stronger than drilled rotors, and they provide some other advantages as well, such as additional biting surfaces.
