I am considering buying some brembo drilled rotors. But do you think its worth it? I know the drilled remain cooler but they must be good if you drive very aggresive, right?

There are 4 main types of rotors: solid, ventilated, slotted and drilled.
Solid is what you find on rear discs. It's just an iron disc. Simple, huh?
Ventilated is what you commonly find on front discs. Its actually 2 discs with metal fins separating them, so that air can pass through the disc from the centre to the edge and help it cool down.
Slotted discs have grooved machined into the disc face. This aids in keeping the disc and the pad clean and dry (the grooves scrape the water off the pad), and gives the pad a little more bite, since the friction area isn't completely smooth. It also tends to resurface the pads every time the brakes are applied, so scoring of the disc is rare and braking is more consistent, but the pads don't last as long.
Drilled is similar to slotted, but it also makes the disc lighter. This aids handling by reducing your unsprung weight, but also means that there is less metal there to take the heat generated when braking. They also have a tendency to warp and crack, because they heat up too fast, and then cool too fast. Some also claim better off-gassing from the pads, but most pads don't have gassing problems these days. They also claim better cooling, because of the slightly higher surface area. However, most repair shops won't service drilled discs.
Generally (except for a few sports cars), drilled rotors are only truly effective on race cars - they can take the heat (since racers aren't on the brakes for very long) and the brakes never really get a chance too cool down all the way before the next corner, anyway - so they don't get a chance to warp until after the race. Besides, they can afford to change then after each race. it's a compromise they're willing to accept, but I wouldn't suggest them for the road. Slotted is your best bet for all-round performance and longevity, especially for on-road use.

Which are better? Regular or Drilled Brake Rotors?

well drilled rotors cool better but if you are not tracking your car, you are wasting your money. The thing about racing on a track is that your brakes get hot for repeated stopping. If they get too hot, they will stop working! But if you take stock brakes, and brembos with drilled rotors and go 100 mph and slam on the brakes, you will stop in nearly the same distance. Because brakes are equal until you do heavy on and off braking that makes them hot!
and by tracking your car I mean racing on a circuit, not dragging. I mean the brembos with slotted or drilled rotors look hot but 99% of people do not need them. Spend your 2-3 k on hot wheels, or something that adds real performance like a turbo.

Brembo actually puts a warning on its drilled rotors that they are not intended for track use. This would seem to imply that these are not really a high-performance product. They are an appearance product. People buy them because they think they look cool.
If you want to stop sooner think pads and brake fluid, not drilled rotors.

Drilled are not really worth it unless you drive so fast that you are experiencing brake fade because solid rotors are not being able to dissipate heat as fast as you want them too. You should take into consideration that you are not going to be able to turn those rotors and they will need to be replaced if they start to warp. You should try going with the slotted if you really believe you drive that hard or at that just stay on solids. there are some complaints that at times the cross drilled rotors begin to crack.

For a street car, drilled rotors are unnecessary. A high quality brake pad is worth more. You don't see drilled rotors in Nascar or F1. Putting holes in your rotor reduces friction area, which in turn reduces braking ability.

The only way any rotor warps is from heat. Drilled rotors reduce heat and brake fade much better than stock stuff. You don't need to out brake a brick wall to appreciate the difference.

the reason the rotors are drilled the way they are is to dissapate heat and keep from excessive brake dust buildup which can cause your brakes to not work as well.. Brembo brakes are an excellent choice for any car especially if you plan on driving fast and stopping hard, there's really no better choice

Drilled are better, I have them on my car. Yeah they look cool, and well they do remain at cool temp (comparing to regular rotors).
But don't get cheap brake pads, go ceramic. Quiet, better, and what brake dust?
