Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
