Which one would each critic pick
| Critic | Kota | Pywen | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.3 | 4.8 | Kota — Pick it if you enjoy assembling your own tools; pick something with batteries if you want to type a request tonight and get a change back. |
| El Crítico | 4.8 | 4.3 | Kota — It edits across files and has no version control operations of its own, so an unwanted change has no undo path the tool can offer you. |
| El Profesor | 4.5 | 5.0 | Pywen — Standardised tool interfaces are the correct instrument for comparing agents fairly, and the row publishes no comparison made with it. |
| La Inversora | 3.8 | 4.5 | Pywen — A hundred and eight stars, a research lab as the author and no commercial entity, so continuity depends on a grant cycle rather than a runway. |
| La Jefa | 4.3 | 4.5 | Pywen — Free across sixty seats, and it is the rare row that names permission control, an approval flow and a trajectory audit as first-class rather than as a roadmap item. |
| El Hacker | 6.3 | 5.0 | Kota — MIT, and the configuration is Lua with custom commands of my own, which is the difference between a settings file and a programmable tool. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
