For eye candy and street use slotted rotors are just fine. Even some drilled rotors last a long time depending on driving habits. For performance, you cant beat a good solid rotor with performance pads. Theyre cheaper too so if you do hpde it keeps the costs down without sacrificing performance.

A solid rotor will withstand more abuse and last longer than any of the others. If you do mostly street driving and want a good rotor with a little bit of bling try the ATE rotors from Tire Rack. They stand up very well and eliptical groove doesnt crack under hard use.

Brake Rotors
If the stock rotors are in good shape, I’d keep them. I spent a good deal of money on GM performance cross drilled and slotted rotors, had them Zinc coated and mounted them on my show car. No heavy driving except for attending shows and they warped. Now that she’s no longer a show car I put the stock rotors back on and I cannot tell any difference. GM knew that most drivers of these cars would push them to their limits so the brake system is very good to begin with. If I had to do it over again, I would zinc and use my original rotors and spend the money elsewhere.

Racers use just slotted or solid. So if you want something that looks good and that you can say is functional, get slotted. Informed people that see drilled know that you are about the look over functionality. I currently have drilled and slotted, and will be going with slotted only next time round.

I have drilled and slotted for street. The look the best, especially with my aftermarket wheels. For the track I just use the stock solid rotors I buy off people upgrading here. I have had my d/s rotors for over 4 yrs with zero issues. But I don't drive it very hard on the street, but I doubt they would make 1 session at the track. If you push your brakes pretty hard on the street, you might want to got slotted or solid. The slotteds will make a bigger brake dust mess than the solids if that matters.

It depends on what you are doing. If you are racing autocross, you should probably get some very light weight drilled rotors. The brakes don't see much heat at all, and there is basically no fade in autocross because of the short track and low speeds. The only reason you would want to use the drilled rotors in autocross is to reduce rotational mass.
I wouldn't use drilled rotors for anything other than autocross.
If you are going to race on a road course, I would definitely suggest solid rotors, as you need to use something disposable. No point in spending mega $$ on rotors if you are going to burn through them in a day, unless you are super rich and can afford to use slotted rotors.
For street use, I prefer slotted rotors.

Ive seen those "dimpled" rotors. They wont crack as easily as a hole that goes all the way through but it depends on the thickness of the material and the heat that it sees. I would just check them for stress cracks periodically.
