Which one would each critic pick
| Critic | agentUniverse | OpenAI Agents Go SDK | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.3 | agentUniverse — Pick it when you want a named collaboration pattern instead of an empty orchestration API; pick MetaGPT if you prefer a role-based crew with more worked examples. |
| El Crítico | 5.8 | 5.5 | agentUniverse — The patterns are the product, so a task that does not fit one leaves you writing the loop yourself, and the review stage doubles the token cost of every iteration. |
| El Profesor | 6.5 | 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 | 6.0 | 5.5 | agentUniverse — Ant Group open-sourced a framework from its own financial production work, which makes the roadmap a function of Ant's needs rather than any user's. |
| La Jefa | 6.0 | 6.0 | no preference |
| El Hacker | 7.8 | 7.5 | 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. |
