It depends on how fast the data you use gets outdated. If its constantly changing and being updated cloud is going to be more efficient.
But if its like Wikipedia or Stackoverflow which you can download entire copies off and run on your local system as an app using Kiwix, the local app will be much more efficient since the majority of the data is not changing much. I have a local copy of Wikipedia that is 3 years old via Kiwix and I haven't visited the online Wikipedia since (all request just go to my local app).
