“It reviews pull requests for logic and ignores style, which is the exact opposite of every human reviewer you have.”

Which one would each critic pick
| Critic | Chorus | Bugbot | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.0 | Chorus — Pick it if you have stopped trusting a model to grade its own homework; pick a single hosted reviewer if one opinion is all your team has time to read. |
| El Crítico | 6.8 | 6.3 | Chorus — Calling it from codex exec requires --dangerously-bypass-approvals-and-sandbox, so the automated path to one of its own reviewers runs with the guard rails switched off. |
| El Profesor | 7.3 | 6.0 | Chorus — Agreement between vendors is used as the pass condition, which substitutes inter-rater consensus for correctness with no published relationship between the two. |
| La Inversora | 6.5 | 8.0 | Bugbot — Metered on individual plans starting at $20, this exists to move solo subscribers onto a team contract, which is the highest-value conversion in the category. |
| La Jefa | 7.3 | 7.0 | Chorus — A global npm install on sixty desks, no seat licence, and a review step that genuinely runs headless: cheap, unmanaged, and invisible to every system I report from. |
| El Hacker | 8.0 | 3.5 | Chorus — Apache-2.0, chorus init registers it as an MCP server with every CLI and IDE it finds, exposing nine tools, and the daemon and its history stay on my machine. |
