Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for solo + free. The best free option, hands down.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
