| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier for data teams. S-tier if you already live in SQL + Python. | B-tier. Still early. Manus is more flexible for less money. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. |
