Which is the best engine for a Ford Fiesta?

I'm looking to buy a Ford Fiesta and I'm not sure which engine option to choose. Could someone provide some recommendations and explain the differences between the options? Thanks!

Based on my personal experience, I would highly recommend the 1.0L EcoBoost engine. It provides a good balance of power and fuel efficiency.

I've done some research and the 1.5L EcoBoost engine seems to be a popular choice among Ford Fiesta owners. It offers more power than the 1.0L option.
