Which one would each critic pick
| Critic | GitLab Duo | Superset | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.0 | no preference |
| El Crítico | 6.5 | 6.3 | GitLab Duo — An agent with shell access and commit rights runs inside the system that holds the source, the pipelines and the deploy credentials, with no container boundary of its own. |
| El Profesor | 7.0 | 6.5 | GitLab Duo — Composition is the design claim: named agents combined into foundational or custom flows, with no published evaluation of whether composition improves the outcome. |
| La Inversora | 8.0 | 7.0 | GitLab Duo — Bundling the entry tier into Premium and Ultimate is an attach-rate play, not a product launch: the AI is defending the subscription, not selling itself. |
| La Jefa | 7.3 | 6.5 | GitLab Duo — The add-on seats are quoted rather than listed, and Agent Platform usage draws down purchased Credits, so sixty developers is one number I cannot compute in advance. |
| El Hacker | 4.8 | 5.3 | Superset — Elastic License 2.0, so I can read and build it but not host it for others; a CLI, and no model settings because the agents bring their own. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
