Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier. Category leader. Nothing else is close yet.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.
