Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier if you already pay Gemini. B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
