Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
