Which one would each critic pick
| Critic | goose | Kon | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.3 | no preference |
| El Crítico | 6.5 | 6.0 | goose — A local agent with terminal execution whose Docker isolation is a --container flag you have to remember, a foundation instead of a vendor, and a bill that depends entirely on which model you point it at. |
| El Profesor | 6.5 | 7.8 | Kon — The core prompt is stated at under 270 tokens and the whole fixed harness at about 1,000, which is an accounting almost nobody in this category publishes. |
| La Inversora | 5.3 | 6.0 | Kon — 353 stars, one author, no price and no hosted piece: a well-made personal project with no mechanism for becoming anything else. |
| La Jefa | 5.8 | 5.8 | no preference |
| El Hacker | 9.3 | 7.8 | goose — Rust, Apache-2.0, every extension an MCP server in YAML, Ollama on my box, a foundation instead of a vendor; this is the one I would build if I had the time. |
