Which one would each critic pick
| Critic | Agent Executor (AX) | CowAgent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 7.0 | CowAgent — Pick CowAgent if you want one assistant answering in WeChat, Feishu and DingTalk from a single install; pick QwenPaw if you want a sandbox under the shell tool. |
| El Crítico | 6.0 | 6.0 | no preference |
| El Profesor | 7.0 | 5.8 | Agent Executor (AX) — Environments are provisioned from suspendable and resumable images and a single-writer controller keeps state consistent, which is a serious answer to distributed agent state. |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 5.8 | 5.5 | Agent Executor (AX) — Free across sixty engineers, it runs unattended so it can carry scheduled work, and the vendor relationship is a public repository with contributions closed. |
| El Hacker | 6.8 | 7.5 | CowAgent — MIT, a Custom provider row for local models or a proxy, one mcp.json with stdio and SSE that hot-reloads, and skills installable from GitHub or ClawHub with a slash command. |
