Kai's verdictS-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.S-tier for speed. When latency is the product, start here.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
