Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
