Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
