Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.A-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.
