What is the difference between Audi Virtual Cockpit and Audi MMI Infotainment System?

I am looking to purchase a new Audi and I see that some models come with the Virtual Cockpit while others come with the MMI Infotainment System. What are the main differences between these two systems and which one should I choose?

The Virtual Cockpit is a fully digital display that replaces traditional gauges with a customizable screen. This provides a more modern and futuristic look to your Audi's interior. On the other hand, the MMI Infotainment System is a central touchscreen display that allows you to control various functions such as navigation, media, and climate control.
