Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.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.S-tier for solo + free. The best free option, hands down.
