Which engine is better for the Audi A4: four-cylinder or V6?

I'm looking to purchase an Audi A4 and I'm torn between the four-cylinder and V6 engine options. Which engine would provide better performance and reliability?

The V6 engine is more powerful and provides better acceleration and torque compared to the four-cylinder. However, the four-cylinder is more fuel-efficient and may be a better option for daily city driving.

I personally prefer the V6 engine because of its smooth and refined driving experience. It also has a more sporty and aggressive engine sound.
