| Kai's verdict | S-tier. Market leader with reason. Start here for serious video. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | 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. |
