A nice normal "blank" rotor, corrosion coating optional but a good idea, is what you want on a truck that's used for any real work.
Drilled rotors are not just for looks. Most people think they dissipate heat better, which is also a fallacy.

When brake pads get hot, they let out a gas, and create a barrier between the pad and rotor. Not good for stopping.

The holes on the rotor allow the gases a place to escape. This causes better stopping power.

The slots in the rotor will do the same, to a lesser degree. Plus the holes/ slots on the rotor will cause the pads to wear quicker.

Cheaper quality rotors will have a greater tendency to crack at the holes.

I have also been using the top end Autozone rotors with good luck on my daily drivers. They come coated to fight rust. They are also made of a higher iron content. They have a higher tolerance to heat. Of all the cars/trucks I have put them on, they haven't warped.

Modern brake pads don't outgas enough to make a difference... at least from everything I've read. If you know otherwise then I'll defer to your expertise.

I've been a HUGE fan of the PowerStop Z36 kit. That's the first upgrade I do on all of my trucks. It's a noticeable difference over stock in braking torque, as well as heat dissipation avoiding rotor hotspots and warping.
I even run the Z26 kit on my Lexus sedan daily beater as I tend to drive it like my race car.

IMHO, for those that upgrade to bigger wheels/tires for the types of trucks we drive, the Z36 upgrade is the perfect matching upgrade to the additional rotating mass. Only thing beyond is going to a big money big brake kit.

Whatever breaking system you decide to go with. If you have DOT 3, which most vehicles leave the factory with, or 4. I would change your brake fluid to DOT 5.1. By changing to 5.1, you increase the boiling point by 100° f. Even if you have DOT 4, your increase by 70°. There are people that blame brake pads when towing heavy when it's your brake fluid.

I've had good luck with OE size brake upgrades along with stainless braided lines. Not night and day but at the very least makes me happy, and isn't that what life is about sometimes.

I've tried every major brake pad out there and I now run the top of the line Powerstop on all my vehicles. I've been doing brakes for 50 years now and I think the Powerstop kits are the way to go. I've got a modded Yukon Denali that gets to 130 real easy and those Powerstops put the whoa on really well with no fade. I had them them on my old Suburban when a brake line popped on my boat trailer coming downhill off a freeway ramp. If I had anything else, I would have blown through the light. Based on my experience you couldn't pay me enough to run anything else. I put them on my wife's Caddy when it was still under warranty because she hated the factory brakes. If I put something else on now she would divorce me. I put them on her Callaway Corvette when the pads she had were still new, the difference was night and day. I did a quick sprint to 130 and nailed the brakes, the car stopped so fast I could feel the blood rushing to my face. I push my vehicles hard and I really like good brakes. I've also flushed all my vehicles brake fluid with the new DOT 3-4 from Amsoil which is also DOT 5.1 compatible. I highly recommend the Powerstop rotors, I've worn them out and no pedal pulsing all the way to the end.

I put Powerstop pads and zinc coated rotors on everything I own, first time they need brakes. For the money, I like their products, and have never had a warped rotor or any other problems.

I think if the rotors warped and you just turn them and replace pads but don't change anything else (i.e. driving habits), they'll warp again.
I've heard turning rotors makes them even more susceptible to warping since there's less mass afterwards. Seems to be true with my experience. I'll be swapping pads and rotors soon and will be giving the Powerstops a try.

I did swap to Hawk pads on the vette and they do seem to work well with stock rotors. Definitely less brake dust to clean off.

I was in a hurry to get my rear brakes done the same day, so I bought a set of cheap Auto zone pads and rotors. (would have had to order the power stops)
The things squeak EVERY time I brake. Didn't notice it in the winter with the windows up. Now that my windows are down, it's really annoying. So now I wasted $200 and am going to get the good brakes and redo the rears.(I knew better)

Here in Ohio, they salt the roads in the winter which wreaks havoc on the truck. I had Hawk pads and power slot rotors on my last truck and ended up having a failure.The pad's backing plate was so rusted the pad de laminated from the backing plate and got lodged. Ended up ruining the rotor because of it. Not slamming Hawk at all, any of the competitors could have failed the same. I just wish they riveted the pads like the old days. Would have prob gotten more life out of them.
