Progressive web apps are kind of a niche product, nations where people aren't upto speed with the internet, web apps will always excel as most of the time, these apps are less resource intensive and requires lower horsepower to run. Basic web browsers on Android does the trick here and therefore penetration levels are higher in developing nations aka third world countries.

This is more evident with what Google is now pushing in Android 7.0 Nougat, with glimpse based apps, you can try out providing user only an instance of the app which is required by the user at that time.

**These apps will always be lighter and easier to develop and can be accessed anywhere through any device. Therefore, if your aim is to get everyone onboard, no matter what internet speed they have on their mobile devices, then progressive web apps are the way to go.

If you want to provide really fluidic and intuitive experience to users and don't feel that you are losing a lot of users than you can go for native apps. They provide better user experience.**
