Which one would each critic pick
| Critic | Claude Agent SDK | Dify | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 8.0 | Dify — Pick Dify when people who are not engineers need to build and change LLM applications; pick n8n if the hard part is connecting systems rather than handling documents and prompts. |
| El Crítico | 6.5 | 7.3 | Dify — The canvas is the source of truth, and a graph edited by dragging does not appear in a pull request, so the review culture around it has to be invented from nothing. |
| El Profesor | 7.0 | 7.8 | Dify — Retrieval, model management and orchestration are separated into distinct subsystems, and finished workflows are exposed over OpenAPI, so an application becomes a callable service. |
| La Inversora | 8.0 | 8.0 | no preference |
| La Jefa | 7.3 | 7.3 | no preference |
| El Hacker | 5.3 | 7.8 | Dify — The licence is not plain Apache-2.0, it is Apache with additional conditions, so read it before you fork; the compose file and any OpenAI-compatible endpoint are the good parts. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
