Which one would each critic pick
| Critic | Herm | Tau | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.3 | Herm — Pick it if approval prompts have trained you to click yes without reading; pick a host-based agent if installing Docker is a fight you would rather skip. |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 7.8 | 7.8 | no preference |
| La Inversora | 6.0 | 7.5 | Tau — 2,607 stars and a real company behind it, publishing a free readable agent: this is developer marketing, and it is the well-executed kind. |
| La Jefa | 6.8 | 6.5 | Herm — It defaults to running the agent in Docker, which means a container runtime on sixty machines, and a Homebrew tap is the closest thing here to a distribution channel. |
| El Hacker | 8.3 | 7.5 | Herm — MIT, and everything is open including the system prompts, the skills and the tools, with nine providers listed and Ollama among them. |
