Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
