Which one would each critic pick
| Critic | GitHub Copilot | ACP Client for VS Code | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.5 | GitHub Copilot — Not the strongest agent here and the easiest to start with; if your code already lives on GitHub, begin here and add a stronger tool where it falls short. |
| El Crítico | 6.5 | 7.0 | ACP Client for VS Code — It serves the agent's file writes against your workspace and runs the commands it asks for under a configurable auto-approve policy. |
| El Profesor | 5.8 | 7.8 | ACP Client for VS Code — Every ACP JSON-RPC message can be inspected in a traffic log, which makes a disagreement about whose fault a failure is answerable rather than rhetorical. |
| La Inversora | 9.3 | 6.8 | GitHub Copilot — Incumbency is the moat: inside the editor, inside the repository host, on invoices approved years ago, with Microsoft's balance sheet behind it. |
| La Jefa | 8.0 | 7.3 | GitHub Copilot — Already on the invoice, with the IP indemnity and policy controls legal asked for on Business and Enterprise; the premium-request meter needs an org-level cap. |
| El Hacker | 4.8 | 7.3 | ACP Client for VS Code — MIT, and the agent list is not a list: anything speaking the protocol can be configured by hand, with no plugin API to learn and no review to pass. |
