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 sales teams. B-tier for solo users.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
