If you look at the demo, all of the payload comes from react and the tailwindcss classes that the shadcn button refers to.
It's dishonest to call this the payload of "one shadcn button" since it's basically all react/tailwindcss fixed cost and not literally a shadcn button.
But still, that's a decently broad demo to fit in a small payload, so the exaggeration kinda takes away from that.
The main thing I care about in client development is the state management solution since that's where most of the complexity comes from, and it's what makes or breaks an approach. In React, I use MobX which I see as the holy grail.
Whether Nue is nice to use or not for me is gonna come down to how nice this is to work with: https://nuejs.org/docs/interactivity.html

Does the ShadCN button work without paying that cost?
Sure. If you just want the shadcn button by itself, it will generate this html: <button class="{tailwindcss classes}" />.
And it has a dependency on some common tailwindcss classes that will get injected into your bundle.
Most shadcn components depend on tailwindcss classes, and how the whole shtick works is that tailwindcss only includes in your bundle the classes that your components use across your app. Which is kind of a clever integration for a ui component 'package manager' for reducing bundle size.
But most importantly, consider that OP's demo has very minimal CSS because they aren't using a CSS framework, and that has nothing to do with their Nue framework. It's not like their Nue framework comes with an optimized answer to tailwindcss/shadcn; you have to bring your own solution.
So if you use tailwindcss/shadcn with React, you'd certainly use it with Nue.
What Nue should do instead is add libraries to either side necessary to reach parity with the other side. Nue has built-in routing, so it would be fair to add react-router-dom to the React side. And they wouldn't have 100 people calling them out for the dumb benchmark.
