Which one would each critic pick
| Critic | Fitten Code | TraeCode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 5.3 | Fitten Code — Pick it if you want capable completion at no cost and your code is not sensitive; pick CodeGeeX when you want a similar deal with a published model behind it. |
| El Crítico | 4.8 | 4.8 | no preference |
| El Profesor | 5.5 | 4.3 | Fitten Code — Project context understanding and multi-step task decomposition are both asserted, and the vendor does not document explicit multi-file diffs or any selection method. |
| La Inversora | 4.8 | 5.3 | TraeCode — Renamed from MarsCode into the vendor's flagship agent brand, with roughly 1.9 million installs carried across, which is a brand consolidation rather than a launch. |
| La Jefa | 4.8 | 4.5 | Fitten Code — Sixty seats at zero is exactly why it spreads before anyone asks me, and there is no contract, no retention policy and no identity integration behind it. |
| El Hacker | 3.5 | 2.5 | Fitten Code — One vendor model, no key of my own, nothing local, no tool protocol and no source. There is not a single surface here I can change. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
