| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for academic research. Nothing else comes close for systematic reviews. |
