Which one would each critic pick
| Critic | Agent S | agentUniverse | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.5 | 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 | 5.8 | 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 | 6.5 | Agent S — The 72.60% headline is the agent plus a Behavior Best-of-N wrapper; the agent alone reaches 66% in the 100-step setting against a prior best of 63.4%. |
| La Inversora | 6.3 | 6.0 | 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 | agentUniverse — No seat cost for sixty engineers and no vendor either, so support is a public issue tracker and the meter is whichever model vendor the configuration points at. |
| El Hacker | 7.5 | 7.8 | agentUniverse — Apache-2.0, pip install agentUniverse, and it speaks MCP in both directions, so my servers plug in and the whole thing can be published as one. |
