Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
