Which one would each critic pick
| Critic | JetBrains AI Assistant | Zoo Code | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.8 | Zoo Code — Pick Zoo Code if you already know Roo Code's modes and want a version somebody is still maintaining; pick Cline if you would rather start from the tool with the largest crowd. |
| El Crítico | 6.5 | 7.0 | Zoo Code — Longer autonomous runs are permitted because a Destructive Command Guard blocks dangerous commands. That is a denylist, and a denylist is only as good as the last thing somebody thought of. |
| El Profesor | 6.8 | 7.0 | Zoo Code — Semble is described as codebase intelligence giving semantic search with no separate indexing step, which is a claim about when the work happens rather than about whether it happens. |
| La Inversora | 7.8 | 7.5 | JetBrains AI Assistant — JetBrains sells this as a layer on IDEs developers already pay for, AI Pro at $10 and Ultimate at $30 with a credit that equals one dollar; pricing so legible it barely needs a sales team. |
| La Jefa | 7.5 | 7.5 | no preference |
| El Hacker | 6.8 | 8.5 | Zoo Code — Apache-2.0, my own keys at the provider's own rates, and Ollama and LM Studio are documented providers, so the whole loop runs on hardware I built if I want it to. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
