Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Market leader with reason. Start here for serious video.
