I love the take on DX > performance.

I have moved away from React to Vue/Svelte over the past 5-6 years, and I am significantly happier as a developer.

In general I believe that the DX on react is subpar when compared with other more modern frameworks, because those frameworks at least attempt to abstract away all of the things that are tedious and cause the majority of React's code clutter.

Few and far in between are the apps that truly need to focus on sheer performance, or have it even matter. And even then, it's unlikely to be a majority focus on the frontend at all.
