Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
