Which one would each critic pick
| Critic | Conductor | Diffblue Agents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.0 | Conductor — Pick Conductor if you run Claude Code, Codex, Cursor or OpenCode on a Mac and want a window per task with the diff beside it; pick Superset if you also need Linux. |
| El Crítico | 5.8 | 5.3 | Conductor — Cloud workspaces are free until the planned usage-based pricing arrives, and there is no source to read while you wait to learn the rate. |
| El Profesor | 6.3 | 6.3 | no preference |
| La Inversora | 6.8 | 7.0 | 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 | 5.8 | 5.5 | Conductor — Teams is invite-only, SAML and SCIM sit in a custom-priced Enterprise tier, it is Mac-only, and CI reaches it only through a beta API on the paid tier; not yet. |
| El Hacker | 3.8 | 4.5 | Diffblue Agents — Proprietary with nothing to read, though the agent platform underneath is one I already run and pay for separately, which is a strange sort of freedom. |
