Which one would each critic pick
| Critic | AG2 | uAgents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.3 | AG2 — Pick AG2 if you want Python agents that call your own functions through a decorator; pick AutoGen if you would rather stay with the original and its research group. |
| El Crítico | 6.0 | 5.5 | AG2 — v1.0 is not a drop-in upgrade, and the older code base continues as a separate ag2-classic package, so this project ships two things under one name. |
| El Profesor | 6.0 | 6.5 | uAgents — Identity is derived deterministically from a seed and messages between agents are signed, so the sender of a message is verified rather than asserted in its payload. |
| La Inversora | 4.8 | 5.8 | uAgents — Fetch.ai publishes it free at 1,635 stars alongside a second package whose purpose is interoperating with the company's own agent marketplace, which is where the business sits. |
| La Jefa | 5.8 | 5.5 | AG2 — Nothing to buy for sixty seats and it runs headless in the CI we already have, but there is no console, no audit trail and no support contract on offer. |
| El Hacker | 7.3 | 6.8 | AG2 — Apache-2.0, pip install ag2[openai], Ollama in the model list, and neither an MCP client nor an MCP server, which in 2026 is the part that annoys me. |
