Which one would each critic pick
| Critic | Diffblue Agents | oh-my-openagent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.5 | oh-my-openagent — Pick oh-my-openagent if you already run OpenCode or Codex CLI and want a planner, a deep worker and an oracle wired in; pick oh-my-claudecode if your agent is Claude Code. |
| El Crítico | 5.3 | 5.5 | oh-my-openagent — The README records that Anthropic blocked OpenCode because of this project, and it was renamed from oh-my-opencode; the host it depends on has already been cut off once. |
| El Profesor | 6.3 | 5.5 | Diffblue Agents — Acceptance is defined as compiling, passing and adding coverage, and the billing unit is net new covered lines, which measures reach rather than correctness. |
| La Inversora | 7.0 | 4.8 | Diffblue Agents — From $1,500 for 5,000 net new lines, an effective thirty cents a line, which is one of the few products here charging for delivered output rather than access. |
| La Jefa | 5.5 | 5.0 | Diffblue Agents — There is no seat price and no free tier, so evaluating this starts at a four-figure commitment, and it covers two languages out of the many we ship. |
| El Hacker | 4.5 | 5.8 | oh-my-openagent — Sustainable Use License 1.0, free for personal and internal use and not for resale, config in .omo/omo.jsonc walked upward from the project, six hosted providers and no local one. |
