Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
