Kai's verdictB-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.S-tier for model-shopping. I use this for every prototype before committing.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
