Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
