What is the difference between the Ford Focus RS and ST models?

I've been researching Ford Focus models and I can't seem to figure out the difference between the RS and ST models. Can anyone explain the technical differences and which one would be a better option for a performance car enthusiast?

The Ford Focus RS is a more powerful and performance-oriented model, with a turbocharged 2.3-liter 4-cylinder engine producing 350 horsepower. The ST model has a turbocharged 2.0-liter 4-cylinder engine, producing 252 horsepower. It also has a sportier suspension and a more aggressive design.

I would personally go with the RS model if you're a performance car enthusiast. It has better handling, more power, and a more aggressive design. The ST model is still a great option for a daily driver though.
