Which one would each critic pick
| Critic | Crab Code | IOSM CLI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 5.8 | no preference |
| El Crítico | 5.0 | 5.0 | no preference |
| El Profesor | 5.8 | 5.0 | Crab Code — Allow and deny rules are declared together with deny stated as always winning, which is a documented conflict resolution rather than an emergent one. |
| La Inversora | 4.0 | 4.5 | IOSM CLI — A hundred and forty-five stars against eight weekly package installs is the signature of a project people bookmark and do not run. |
| La Jefa | 4.8 | 5.0 | IOSM CLI — No licence cost across sixty engineers, and the layered policy engine is the only artefact here I could put in front of a security reviewer without apologising. |
| El Hacker | 6.5 | 6.0 | Crab Code — MIT, my key, five providers to route between, and a build from a clone, which is the install path I trust most because it is the one I can read. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
