| Kai's verdict | 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. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. | A-tier. Bet on this one — the Sparkpage format is genuinely new. |
