Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
