Brush motors have been used for a long time and are still used in many applications. They are simple, reliable and cost-effective. However, they have some drawbacks, such as limited lifespan, high maintenance requirements, and low efficiency.
On the other hand, brushless motors are more efficient, have a longer lifespan, and require less maintenance. They are also quieter and produce less heat. However, they are generally more expensive and more complex than brush motors.
The choice of motor depends on the specific application, budget, and performance requirements. If you are looking for a low-cost option and don't require high performance, a brushed motor may be a good choice. If you need higher performance, efficiency, and durability, a brushless motor would be a better choice.
