Which one would each critic pick
| Critic | Gitar | OpenReview | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 5.8 | Gitar — Pick Gitar if your reviewers are drowning and you want a bot that argues back in the thread; pick CodeRabbit if you only want the comments. |
| El Crítico | 5.8 | 5.3 | Gitar — The same agent that reviews the branch also commits to it, and the Pro tier lets it auto-approve and block merges, which collapses author and reviewer. |
| El Profesor | 6.5 | 7.0 | OpenReview — The review executes linters, formatters and the test suite inside the environment rather than reasoning about them, which is the only honest form of verification here. |
| La Inversora | 7.0 | 5.3 | Gitar — The ownership question is already answered: Gitar is joining Sonar, so this is now a feature inside a code-quality suite rather than a standalone bet. |
| La Jefa | 6.5 | 5.3 | Gitar — Core is $20 and Pro $40 per user per month, so sixty engineers is $1,200 or $2,400 before anything else, and self-hosted code hosting is Enterprise only. |
| El Hacker | 4.0 | 5.8 | OpenReview — The source is public and there is no licence declared, which means legally I have nothing, and the model is fixed to one vendor with no substitution. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
