Which one would each critic pick
| Critic | Kota | Plandex | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.3 | 5.3 | no preference |
| El Crítico | 4.8 | 4.5 | Kota — It edits across files and has no version control operations of its own, so an unwanted change has no undo path the tool can offer you. |
| El Profesor | 4.5 | 5.5 | Plandex — The cumulative diff sandbox is the most principled edit-staging design among terminal agents, and the 2M-token context claim has no measurement behind it. |
| La Inversora | 3.8 | 3.0 | Kota — 100 stars, two public mentions in a year and zero measured adoption, from a single author publishing through a package registry. |
| La Jefa | 4.3 | 3.5 | Kota — The one thing here my team could use is embedding it inside our own service, and there is no console, no single sign-on and nothing that runs unattended. |
| El Hacker | 6.3 | 6.8 | Plandex — MIT, runs entirely on my box with start_local.sh, talks to Ollama or OpenRouter, and I would be the maintainer, which is the honest price of the diff sandbox. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
