In my experience LLMs write better svelte code then React code, as there's fewer footguns (e.g. useEffect is much more brittle in React)

This is interesting but in my experience an avoidable issue if you force the LLM to write extensive E2E tests before writing any code. I also force mine to run performance benchmarks against any new commit before it’s committed.

I have backend bugs that I need to manage myself, usually from unknown-unknowns that I don’t think I can easily avoid, but I never have frontend bugs (since Opus 4.6 anyway).

And if you force the LLM to write extensive E2E tests and performance benchmarks before writing any Svelte code, you're even better off.

In the "Unix Haters Handbook", "X-Windows Disaster" chapter, "Ice Cube: The Lethal Weapon" section, I quoted Jamie Zawinski, whose timeless and tactile observation also applies to React:

You and Jamie sure landed on opposite sides of the AI debate.
