Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
