What is the difference between Audi A8 55 TFSI versus Audi A8 60 TFSI?

I am looking to purchase an Audi A8 and I noticed there are two different engine options, the 55 TFSI and the 60 TFSI. Could you explain the differences between the two? Which one would you recommend and why?

The main difference between the Audi A8 55 TFSI and the Audi A8 60 TFSI is the engine size and power. The 55 TFSI has a 3.0-liter V6 engine while the 60 TFSI has a 4.0-liter V8 engine. This means the 60 TFSI will have more horsepower and torque, resulting in a more powerful and responsive driving experience. If you want a more exhilarating driving experience, then the 60 TFSI would be the better option.
