Most native apps are some half gig large where even the heaviest website is a few mb. They dont let you highlight text and have other bizarre design choices. Even worse, they request importing contacts list which isnt even an option on the web.
Native apps could be butter but more often than not they are like margarine. Smooth, oily, and not good for you.
Reddit always asks you to use its native app, for example. Why the fuck would I care so much about Reddit that I want it outside of my browser? Same goes for any other website.
But I'll eat my hat before I'll install Reddit's own app. Reddit killing off 3rd party apps is why I post here and not there.
