Do you think ball screw is exactly better than traditional rack & pinion?

not exactly. Both systems have their advantages and disadvantages

Backlash:
One of the main advantages of ball screws over rack & pinions is that they have lower backlash. Backlash refers to the amount of "play" or "slop" between the screw and the nut. In a steering system, backlash can lead to a lack of precision and responsiveness. Ball screws, however, have minimal backlash due to their design, which involves rolling balls between the screw and the nut. This results in smoother and more accurate steering.
Wear:
Another advantage of ball screws is that they wear slower than rack & pinions. Rack & pinions have teeth that rub against each other, which leads to more wear and tear over time. Ball screws, on the other hand, have rolling balls that reduce friction and wear. This means that ball screws last longer and require less maintenance.

ball screws are generally more expensive than rack & pinions. This is because they are more complex to manufacture and require higher precision. Rack & pinions are simpler in design and can be mass-produced at a lower cost. However, the initial investment in ball screws can pay off in the long run due to their longer lifespan and lower maintenance costs.
Performance:
In terms of performance, both ball screws and rack & pinions can provide good steering capabilities. However, ball screws are generally more precise and offer better feedback, which can be important for high-performance vehicles. Rack & pinions, on the other hand, can provide faster steering and are often used in sports cars for this reason.
So you decide which one is more suitable for you according to your own situation
