What's in it for you as a user is that the app exists at all. A lot of apps either aren't meant to be profitable (government services apps, ngos etc) or won't be profitable enough after paying for developing the app 3x. Building them as a PWA is what makes them viable at all.

If users are willing to pay the extra cost for a carefully handcrafted native app for any particular use case the market will step up and provide it.
