Subaru Legacy 2.0i or 2.0D ?

Hello, I would like to buy a used car Subaru Legacy from 2012 and am still unsure if it should become a petrol or diesel. What I read on the internet: In addition to advantages in fuel consumption, the diesel should also have a better response behavior. Apart from the engine sound, the diesel is therefore more recommended. Furthermore, the diesel control chain and no timing belt have, which should keep the follow-up costs slightly lower than the gasoline. Can you confirm it? Or should you go to the petrol truck?
