Which one would each critic pick
| Critic | Snow CLI | zerostack | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.8 | no preference |
| El Crítico | 6.0 | 6.3 | zerostack — The isolation flag is best-effort: with neither backend present it proceeds without protection unless you also pass the flag that makes it mandatory. |
| El Profesor | 7.0 | 7.0 | no preference |
| La Inversora | 6.3 | 5.0 | Snow CLI — 1,063 stars, one maintainer and no price: an unusually complete product built as a gift, which is the least predictable supply arrangement there is. |
| La Jefa | 5.5 | 5.5 | no preference |
| El Hacker | 7.3 | 8.5 | zerostack — GPL-3.0-only, `cargo install zerostack`, and the provider list runs OpenRouter, Ollama, vLLM and LiteLLM, so the model is mine to place. |
