Kai's verdictB-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.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. S-tier if you self-host. The reason open-source image gen matters.
