Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for sales teams. B-tier for solo users.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
