Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Close second to Cursor. If $5/mo matters, start here.
