Which one would each critic pick
| Critic | AWS Transform | Jules | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.8 | Jules — Use Jules for the backlog you never get to, fifteen free tasks a day on a personal Google account, and do not adopt it as a team tool because the paid plans do not accept business accounts yet. |
| El Crítico | 5.8 | 6.3 | Jules — Jules runs your repo in a VM you cannot inspect on a model you cannot choose, and the failure mode is a pull request built on an environment that never installed correctly. |
| El Profesor | 6.0 | 6.3 | Jules — Jules has the correct autonomous architecture, an isolated VM, a plan reviewed before edits, tests run in place, and publishes no benchmark by which to judge what it does with it. |
| La Inversora | 8.0 | 6.0 | AWS Transform — Billed straight through the AWS account, and the pricing page did not render a readable rate card at listing, which is a strong position and a weak disclosure. |
| La Jefa | 6.8 | 4.8 | AWS Transform — Seats are the wrong unit here; this is a programme billed to an account we already hold, with identity and audit inherited from the cloud contract legal signed. |
| El Hacker | 3.5 | 4.3 | Jules — A closed VM, Gemini only, a curated MCP list and no key of my own; the CLI and REST API are the only handles, and they are decent handles. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
