| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier for ops automation. B-tier for simple copy (use Claude). | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. |
