| Best for | Grad students, researchers, anyone doing literature reviews. | Anyone who wants top-tier video quality for less. | Teams with GitHub already. Devs who don't want to change IDEs. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. |

| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
