Kai's verdictA-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.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
