Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.B-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.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
