Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.
