Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
