Come on man, this is the whole reason Duolingo was people's favourite language learning app, or people claim they like iPhones over Android phones or Photoshop over Canva. These apps and devices all work, but which one is good or better is a debate. People have preferences; some apps in a category are easier to use than others, and some apps have branding that signals status.
