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.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier in the agent category. The first one I'd give to a non-technical friend.
