Which one would each critic pick
| Critic | ChatDev | motleycrew | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.8 | 6.0 | motleycrew — Pick motleycrew if you already have agents written against other Python frameworks; pick one of those frameworks directly if you are starting from nothing. |
| El Crítico | 5.8 | 5.3 | ChatDev — Version 2.0 turned a research project into a zero-code console and pushed the classic line to a legacy branch, so the version every paper describes is now the old one. |
| El Profesor | 4.8 | 6.5 | motleycrew — Tasks and their data are stored in a knowledge graph that also controls the flow of the system, which makes execution order an inspectable structure rather than a prompt convention. |
| La Inversora | 5.5 | 5.5 | no preference |
| La Jefa | 4.8 | 4.8 | no preference |
| El Hacker | 5.8 | 5.8 | no preference |
