Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier. Category leader. Nothing else is close yet.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Market leader with reason. Start here for serious video.
