| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. |
