What is the function of the Audi A6's Drive Select feature?

I'm looking to buy an Audi A6 and noticed it has a Drive Select feature. Can you explain what it does and if it's worth getting?

The Drive Select feature on the Audi A6 allows you to customize your driving experience by adjusting the suspension, steering, and transmission for different driving modes. In Comfort mode, the suspension and steering are more relaxed for a smoother ride, while in Dynamic mode, the suspension and steering are stiffer for a sportier feel. It's definitely worth getting if you like the option to personalize your driving experience.
