Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
