Which one would each critic pick
| Critic | II-Agent | Jules | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 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 | 6.5 | 6.3 | II-Agent — The interesting pipeline is research to artefact with citations attached, which is a verifiable output format, and nothing published measures how often the citations hold. |
| La Inversora | 6.3 | 6.0 | II-Agent — A permissive core with a hosted app on top and no published price is a distribution experiment, not yet a company, and the experiment is running on the model bill. |
| La Jefa | 5.5 | 4.8 | II-Agent — Zero per seat and a Docker Compose deployment my platform team can run, but nothing here executes unattended, so it never becomes part of a pipeline. |
| El Hacker | 7.8 | 4.3 | II-Agent — Apache-2.0, my keys, and the model config takes Vertex, Azure or a self-hosted endpoint, so inference can stay on hardware I picked. |
