Kai's verdict	A-tier in its niche. The only one that actually gets emotion right.	A-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.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
