Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
