What is the best engine type for the Ford Fiesta?

I am considering buying a Ford Fiesta and I am torn between the different engine types available. What are the differences between the EcoBoost, Duratec, and EcoBlue engines? Which one would you recommend?

In my opinion, the EcoBoost engine is the best option for the Ford Fiesta. It offers a good balance of performance and fuel efficiency.

I have been driving a Ford Fiesta with the Duratec engine for years and have had no complaints. It may not have the same power as the EcoBoost, but it's still a reliable choice.

I recently upgraded to a Ford Fiesta with the EcoBlue engine and I am extremely satisfied. It has great fuel economy and plenty of power.
