Kai's verdict	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	B-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. Bet on this one — the Sparkpage format is genuinely new.
