Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Useful for first drafts. v0 is the better bet for shipping code.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.
