Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier if you already pay Gemini. B-tier standalone.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
