I appreciate that you’re getting to the crux of the matter instead of downvoting.

In our experience elevating the web metrics in Next.js takes the same expertise as doing it in any other framework. Our experience with Vertx and Microsoft’s dotnet web frameworks have been good, but Next.js got us to a fast, featureful, performant website sooner and with more flexibility around requirements. I won’t pass judgement on rust frameworks I haven’t used, but it’s just to say that in an honest accounting, a naked backend framework is less than half the product when you’re talking about web applications actually worth making with original ideas. Unless you work at Google.
