What do you do? Ionic storage vs Firebase


What do you do?

When making a mobile app (Ionic 3 or 4), when should one use Ionic/native storage, and when should one use Firebase? Or do people just use Firebase (real time database, or Firestore, or cloud hosting) for all the storage and ignore local and Ionic storage?


I use Firebase since I need to manage user settings from my back end, and maintain account data even if the user has replaced/changed their phones.
