Stores really turned me off in Svelte 4 so I was eager to start using Svelte 5. I've been using Sveltekit and Svelte 5 for a new project and I have to say... React's productivity is still unmatched, even if the Sveltekit and Svelte tech is technically better.

A couple of things that I found really annoying: all pages being named `+page.server.ts` or `+page.svelte` or a variation of that makes it hard to easily search for code. The tooling for Svelte is also separate from `tsc` and ESLint, making it tricker to both integrate into CI and use in dev.

And then there's just weird incompatibility stuff with the previous version. For instance, most Svelte packages still use stores, like SuperForms, so you have to contend with two versions of the world, making writing code really confusing at times. Plus, Svelte HMR is still kinda early AFAICT, so it will clobber your state when a Svelte module reloads.

I _really_ want to like Svelte. It's significantly faster to render and I like the ideas behind it. But React's productivity is unmatched.
