If you are not tracking the car the OEM ACDelcos “heavy duty” are fine or you can upgrade to Power Stops slotted and drilled if want that look. Unlike brake pads where each brand and compound can feel, sound and dust at various levels rotors are basically all the same unless you get into racing style 2 piece directional ones. The only reason to upgrade to that level is better cooling on track and less rotational mass. For street driving you’ll never notice the difference between rotor brands, it’s just a slab of iron you slowly grind away.

Often warpped rotors are just pad deposits. Given the labor involved to turn or resurface them most people will just replace as they are very much a disposable wear and tear item.
