Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
