Which one would each critic pick
| Critic | Atomic Agent | pi_agent_rust | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.5 | pi_agent_rust — Pick it if agent startup time is the thing that annoys you daily; pick Aider if you want a mature terminal agent and can wait a second for it to wake up. |
| El Crítico | 5.5 | 5.8 | pi_agent_rust — It ships compatibility handling for the differences between OpenAI-compatible APIs, which is a matrix one maintainer now owns for every provider anyone points it at. |
| El Profesor | 5.5 | 5.8 | pi_agent_rust — The premise is that managed runtimes add startup and memory overhead and that streaming breaks under load, and the repository publishes no measurement of either claim. |
| La Inversora | 5.5 | 5.5 | no preference |
| La Jefa | 5.5 | 5.3 | Atomic Agent — Nothing per seat and nothing leaves the workstation, which is the shortest data review I will run, and there is no console over sixty of them. |
| El Hacker | 8.0 | 7.5 | Atomic Agent — MIT, a llama.cpp build underneath, MCP servers wired in, and it embeds over HTTP or as a Tauri sidecar, so it becomes a component in things I build. |
