Ask HN: Are progressive web apps(PWA) as good as native apps now?

When Google pitched PWA, I being a web developer was quite excited. No need to build different apps for different platform, single app with all features of native app like Notification, works offline, installable etc

At present PWAs have most features which were planned. Still we don't see big names ditching native apps for PWAs. Companies which has good PWA(Twitter, Quora, Reddit) recommends user to switch to native app.

Which features are holding PWAs back from being as good as native apps?
