Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier for social/casual. B-tier for serious work. Good entry point.B-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.
