Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.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.
