Kai's verdictS-tier. Market leader with reason. Start here for serious video.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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
