Which one would each critic pick
| Critic | Lemma | Proliferate | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 7.3 | Proliferate — Pick it if you want several agents working at once and each behaving exactly as its own CLI does; pick Warren if the runs belong on a server rather than your laptop. |
| El Crítico | 6.3 | 6.3 | no preference |
| El Profesor | 7.0 | 7.0 | no preference |
| La Inversora | 6.3 | 6.0 | Lemma — Self-host free and pay for Lemma Cloud when you would rather not run it: the correct shape for infrastructure, and the one with the thinnest margins. |
| La Jefa | 6.5 | 5.5 | Lemma — Work starts from a schedule, a webhook or a table event with approval steps in the middle, which is the first question procurement asks about automation. |
| El Hacker | 7.8 | 7.8 | no preference |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
