Which one would each critic pick
| Critic | fx | Oh My Coder | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.5 | Oh My Coder — Pick Oh My Coder if the tools everyone recommends are unreachable from where you work; pick Claude Code the moment they are not, and the project documents that move for you. |
| El Crítico | 5.3 | 5.5 | Oh My Coder — Thirty-one specialist agents ship in the box and nothing published says how one gets chosen. A cast that large is a routing problem, and routing failures are silent. |
| El Profesor | 6.3 | 5.5 | fx — Output stays shell-shaped rather than a full-screen interface, and it reads a competitor-compatible tool configuration file, which makes the setup portable between agents. |
| La Inversora | 5.8 | 5.5 | 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 | 4.8 | 4.8 | no preference |
| El Hacker | 7.0 | 6.5 | 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. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
