Which one would each critic pick
| Critic | Kun | Theia IDE | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 7.0 | Theia IDE — Pick Theia if you want an editor with an agent and no subscription attached; pick Zed if speed matters more to you than owning the configuration. |
| El Crítico | 5.8 | 6.8 | Theia IDE — It runs VS Code extensions from Open VSX rather than the Microsoft marketplace, so an extension your team depends on may simply not be there. |
| El Profesor | 6.5 | 7.5 | Theia IDE — An Orchestrator agent routes a request to a specialised one, which is explicit dispatch rather than a single prompt pretending to be several. |
| La Inversora | 5.0 | 7.0 | Theia IDE — Foundation stewardship is the anti-acquisition structure: there is no cap table to change hands, which is a stronger guarantee than any startup on this board can offer. |
| La Jefa | 4.8 | 6.8 | Theia IDE — Zero licence cost across sixty desks and a desktop install on each of them, with no console, no central policy and nothing that runs in a pipeline. |
| El Hacker | 6.5 | 8.5 | Theia IDE — EPL-2.0, every prompt template is editable by me, and Ollama or llamafile are documented providers, so the whole editor runs with nothing leaving the machine. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
