Which one would each critic pick
| Critic | cubic | Open Code Review | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | cubic — Pick cubic if you are on GitHub and want a reviewer whose CLI also runs on uncommitted changes from inside Cursor, Claude Code or Codex; pick Bito if you are on GitLab or Bitbucket. |
| El Crítico | 6.5 | 6.0 | cubic — Background agents give the GitHub App write access so the reviewer can commit fixes; the docs limit that scope to fix branches and promise never to push to main. |
| El Profesor | 6.5 | 6.8 | Open Code Review — The reported figures come from a self-authored 200-pull-request benchmark claiming higher precision at roughly a ninth of the tokens, with no methodology published to check either number. |
| La Inversora | 6.3 | 6.8 | Open Code Review — A hyperscaler released this free in May 2026 with nothing attached to sell, so its lifespan is a function of one internal team's mandate, not of a market. |
| La Jefa | 6.0 | 6.0 | no preference |
| El Hacker | 4.0 | 8.0 | Open Code Review — Apache-2.0, a global npm install, and an MCP client, so I can bolt my own servers onto the review and read every rule that produced a comment. |
