Which one would each critic pick
| Critic | Agent Deck | Clay Studio | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.0 | Agent Deck — Pick it if you keep four things in flight at once; pick a plain tmux config if one agent at a time is the honest description of your day. |
| El Crítico | 6.5 | 6.5 | no preference |
| El Profesor | 7.0 | 7.0 | no preference |
| La Inversora | 6.8 | 6.3 | Agent Deck — 839 stars, one GitHub handle and nothing to charge for: session managers are connective tissue between products other people fund. |
| La Jefa | 5.8 | 6.0 | Clay Studio — A daemon we host, a browser workspace for sixty people, and no directory behind it: shared access without single sign-on is an access review I cannot pass. |
| El Hacker | 7.5 | 7.8 | Clay Studio — MIT, ten agent CLIs behind one workspace, and MCP servers connected and managed from that workspace rather than configured ten times in ten different files. |
