Which one would each critic pick
| Critic | Juggler | ZhikunCode | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.3 | Juggler — Pick it when you want to see what the model is doing and change it mid-flight; pick a terminal agent if a scrollback has never actually bothered you. |
| El Crítico | 6.8 | 6.5 | Juggler — A session is a collaborative document and several clients can attach to one at once, and nothing documents what happens when two of them edit the context together. |
| El Profesor | 7.8 | 7.3 | Juggler — Context items, approvals, thread structure and the raw system prompt are laid out as inspectable columns, so the prompt is an object the user edits rather than an internal detail. |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 6.3 | 6.8 | ZhikunCode — The verification framework keeps screenshots, commands, console output, tests, video, HAR files and diffs per change, which is the review artefact I usually have to assemble. |
| El Hacker | 8.0 | 8.0 | no preference |
