| Kai's verdict | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Bet on this one — the Sparkpage format is genuinely new. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. |
