“It writes your code and also your slide deck, which is the most accurate description of an engineering week ever shipped as a feature list.”

Which one would each critic pick
| Critic | Cursor | Kun | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 6.3 | Cursor — The best editor experience today, with a subscription that turns into a meter the moment you push the agent hard. |
| El Crítico | 6.5 | 5.8 | Cursor — The sandbox is a property of the run mode you pick, and Run Everything drops it, while the pricing page turns limits into a ladder of tiers to climb. |
| El Profesor | 6.0 | 6.5 | Kun — The graphical client and the terminal client both attach to one local runtime, so threads, plans and approvals are shared state rather than two synchronised copies. |
| La Inversora | 8.3 | 5.0 | Cursor — Real revenue, real pricing power, an in-house model, and a dependency on the labs it competes with for every frontier request. |
| La Jefa | 7.5 | 4.8 | Cursor — Teams at $40 per user with SSO, but SCIM, audit logs and auto-run controls sit behind a custom Enterprise quote. |
| El Hacker | 4.5 | 6.5 | Kun — PolyForm Noncommercial, so I can read it and never ship a competing fork, but Ollama is a named preset and every base URL is editable. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
