Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for creators training custom looks. B-tier for general use.S-tier in the agent category. The first one I'd give to a non-technical friend.
