Disc brake rotors can indeed be categorized into different styles based on their design, and both hub-style and hubless-style configurations are prevalent in automotive applications. The hub-style rotor includes a central hub that connects directly to the wheel hub, making it a common choice in many vehicles as it provides robust structural support and effective heat dissipation.

On the other hand, hubless-style rotors do not have a central hub. Instead, they rely on the wheel assembly to support the rotor, which can reduce weight while allowing for greater flexibility in certain applications or performance scenarios. This design can be advantageous in performance vehicles where reducing unsprung weight is crucial to improve handling and acceleration.

Therefore, both technicians are correct in their assertions about the types of disc brake rotors available in automotive systems. Understanding these distinctions is important for professionals in the field, as it affects rotor selection based on vehicle design, performance needs, and service requirements.
