Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier for data teams. S-tier if you already live in SQL + Python.
