Kai's verdictB-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.S-tier. Market leader with reason. Start here for serious video.S-tier for speed. When latency is the product, start here.
