Which one would each critic pick
| Critic | FuXi | fx | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.0 | FuXi — Pick it if you want one downloaded binary and no runtime to install; pick OpenCode when you would rather your terminal agent be something you can read. |
| El Crítico | 5.3 | 5.3 | no preference |
| El Profesor | 6.3 | 6.3 | no preference |
| La Inversora | 5.3 | 5.8 | fx — A labs project rather than a product, with billing that runs through the parent's inference routing service, so the free binary is the metered path in. |
| La Jefa | 5.0 | 4.8 | FuXi — Zero licence cost for sixty and a documented token command for headless runs, but a one-month-old preview from a vendor with no company details is not a supplier. |
| El Hacker | 6.5 | 7.0 | fx — Apache-2.0 compiled from Zig, and every tool server stays disconnected until I approve it by name, which is the consent model everyone else skipped. |
