Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
