Limited functionalities are available compared to a native app. Most of the client requirements can be satisfied by PWA features themselves. For them, we suggest PWA only and give them an idea to convert their PWA as an Android App using TWA if they want to deploy in Playstore.

But in reality, most everyone in the software development industry believe web apps and hybrid apps have slower performance than native apps. Still, having a PWA means going through the classic download and install process that users expect with mobile apps. But this is a good thing as PWAs can always be readily available from the user’s device.
