Kai's verdict	A-tier. Best free agentic option in VS Code. Use with Claude for best results.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.
