The app might have better UI/UX because developers have more possibilities with native UI toolkits compared to a webapp running inside a browser.
The app can also simply be better made than the website (or have more features), when the developers prioritize the app in that way and leave the website as a second-rate app (they don’t need to do that but they might).
However, the app can harvest much more data from you (and your device) than a website can (although a website can also gather quite a bit).
Plus, the app can lock you into a specific platform-specific ecosystem. For example if the app requires Google’s DRM (Play Services Integrity), then the app will only run on Google-sanctioned Android variants, not anywhere else.
So there’s pros and cons. Usually, the cons are more severe. A webapp is overall a bit less privacy invasive and truly works cross-platform and cross-device.
