Which one would each critic pick
| Critic | Agent S | OpenAI Agents Go SDK | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.3 | Agent S — Pick Agent S if you need something that drives real desktop applications; pick Browser Use when the work happens inside a browser and nothing else. |
| El Crítico | 6.3 | 5.5 | Agent S — The prerequisites say plainly that the agent runs Python code to control your computer, and the board records no container sandbox, so the blast radius is your desktop. |
| El Profesor | 6.8 | 7.5 | OpenAI Agents Go SDK — The loop is bounded by an explicit turn limit and wrapped in typed guardrails on both input and output, which places two hard stops around a process that otherwise has none. |
| La Inversora | 6.3 | 5.5 | Agent S — Simular publishes the papers and sells the hosted version, so the open framework is a recruiting document and a demo funnel for a cloud product. |
| La Jefa | 5.0 | 6.0 | OpenAI Agents Go SDK — Nothing to license for sixty engineers and nothing to install on their desks, but it is a library in one language, so the audience is whichever teams already write in it. |
| El Hacker | 7.5 | 7.5 | no preference |
