Kai's verdictB-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.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
