Which one would each critic pick
| Critic | AgentHub | Pi Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.3 | no preference |
| El Crítico | 6.3 | 6.5 | Pi Agent — The application bundles the web server, the language runtime and a pinned version of the SDK, so upgrades arrive on the packager's schedule and not the agent's. |
| El Profesor | 6.8 | 7.0 | Pi Agent — Context usage and cost are displayed live and a conversation can be forked from any earlier message, which makes the session a tree instead of a line. |
| La Inversora | 6.0 | 6.0 | no preference |
| La Jefa | 6.3 | 6.0 | AgentHub — Free across sixty seats and disqualified for most of them: it ships for macOS only, so this is a tool for an all-Apple team or for nobody. |
| El Hacker | 7.3 | 6.8 | AgentHub — MIT and Swift, and it ships its own MCP server that registers into ~/.codex/config.toml, so the sessions it hosts get tools I wrote rather than tools it chose. |
