Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Market leader with reason. Start here for serious video.A-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
