Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.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.
