Which one would each critic pick
| Critic | cmux | Hermes Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | cmux — Pick it if you run several agents on a Mac and your terminal has become a graveyard of tabs; pick Warp if you want the terminal itself to be the agent. |
| El Crítico | 6.5 | 6.3 | cmux — A programmable browser lives inside the same application that hosts your agents and your remote sessions, and no sandbox is recorded anywhere on the row. |
| El Profesor | 6.8 | 6.8 | no preference |
| La Inversora | 6.0 | 6.8 | Hermes Agent — Nous Research gives the agent away and sells the Portal: 300-plus models, search, images and a cloud browser under one subscription from $20 a month, with a free tier as the funnel. |
| La Jefa | 5.5 | 5.3 | cmux — It runs on macOS and nothing else, which decides this before cost, and there is no headless mode, no SSO and no audit trail to discuss afterwards. |
| El Hacker | 7.5 | 8.5 | Hermes Agent — MIT, ~/.hermes with hermes config set, any OpenAI-compatible endpoint, Ollama, vLLM and llama.cpp, and MCP servers configured from the docs page; I can run this air-gapped. |
