Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Bet on this one — the Sparkpage format is genuinely new.
