Which one would each critic pick
| Critic | Aizen | Ally | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.0 | no preference |
| El Crítico | 5.3 | 5.0 | Aizen — The install script and the cargo command both fetch from aizen-stack/aizen, while the project the row records is talmetis-labs/aizen. Two orgs, one binary, no explanation. |
| El Profesor | 6.0 | 5.8 | Aizen — Context comes from a codebase index with semantic search and an LSP server, so retrieval is grounded in a parse rather than in string matching. No evaluation accompanies the claim. |
| La Inversora | 5.0 | 5.0 | no preference |
| La Jefa | 4.5 | 4.8 | Ally — Sixty desks at no licence cost and nothing to govern them with: no single sign-on, no directory sync, no retention policy and no central log. |
| El Hacker | 7.0 | 7.0 | no preference |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
