Which one would each critic pick
| Critic | Aider | Mistral Vibe | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 6.8 | Aider — Pick Aider if you want to see every diff and steer every step; pick Claude Code if you want the agent to find the files and run on its own. |
| El Crítico | 7.3 | 6.0 | Aider — Every edit is a real edit on your disk with no sandbox, and auto-commit is the one mitigation standing between a bad command and your afternoon. |
| El Profesor | 8.3 | 6.0 | Aider — The most legible architecture on the board, with a published harness; the SWE-bench numbers are from 2024 and should be read as history, not as a claim. |
| La Inversora | 5.3 | 6.3 | Mistral Vibe — Mistral renamed Le Chat to Vibe on May 28, 2026 and put the coding agent at the center of the consumer brand, a company betting its front door on developers. |
| La Jefa | 5.5 | 6.3 | Mistral Vibe — Team is $24.99 per user, $1,499.40 a month for sixty, and Enterprise is custom, which is the phrase that adds a quarter to procurement. |
| El Hacker | 9.0 | 8.0 | Aider — Python I can read, prompts in the repo, .aider.conf.yml for model and edit format, --model ollama/anything for an air-gapped box; MCP is the one gap. |
