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.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier. Best for teaching a kid to code in 2026.
