Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
