Kai's verdictA-tier in its niche. The only one that actually gets emotion right.B-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.A-tier for data teams. S-tier if you already live in SQL + Python.
