It's good enough when you can't afford to build native or your intended audience/product isn't primarily mobile, sure. Just clicking through the samples at pwa.rocks - a good portion of these are demos/prototypes. Some are just well designed responsive websites that aren't much else than a brochure/ecommerce sites. Sure, it's not hard to format content for mobile and make it look nice. There's a couple of good ones on this list, but for the most part I wouldn't put this list against a list of top ten well designed native apps. They're just not comparable. That said, I'm not arguing against building out nice mobile responsive sites (and this is something that I think gets forgotten way too much with "rich interface" single-page app designs that are all the craze on desktop). I'm a strong believer that every site should be written with mobile in mind first unless there are strong use cases to argue against it. Don't ever force your users to install an app to consume your product unless the product itself is the app.
