Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for data teams. S-tier if you already live in SQL + Python.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for ops automation. B-tier for simple copy (use Claude).
