Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
