The B2B productivity/collaboration app space — where you can expect that all your users are mainly using full PCs — is firmly all-in on in-browser web-apps, with their mobile experiences being second-class afterthoughts.
I imagine apps are better at being apps than a web browser, and due to their complexity webapps are also tightly coupled to a specific brand and version of browser, so you have less compatibility problems by bundling your preferred vm with your application.
I'd argue today that "apps" do pretty well whether they're in a browser or native. Native Slack is pretty good. Web Google Docs/Sheets is pretty good. VSCode is almost the same regardless of where you run it. But equally, Sketch and Ableton Live are also pretty good. Native Teams and Zoom are travesties of usability and stability.
Basically, I don't see consistent patterns of good or bad between web and native apps to justify your comment that "apps are better at being apps than a web browser".
Most GUI apps, native or otherwise, get associated with a brand. Especially the good ones. I'd buy Ableton swag, I love the brand that much.
The VAST bulk of web apps are NOT browser version specific. It's largely only bespoke, internal corporate apps that are tied to one version of a browser.
