Which one would each critic pick
| Critic | Claude Code Haha | Magi | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 5.8 | Claude Code Haha — Pick Claude Code Haha if you want branches, worktrees and turn-by-turn diffs in a window; pick Claude Code in the terminal if a wrapper is one layer too many. |
| El Crítico | 5.5 | 5.0 | Claude Code Haha — One person's spare-time project ships a skill marketplace, computer control, five chat-app relays and desktop pets, and each of those is a surface somebody has to keep safe. |
| El Profesor | 6.3 | 7.0 | Magi — One run trace records the goal, the derived tasks, every tool call, the resulting changes and the verification results, which makes a completed run auditable end to end. |
| La Inversora | 5.3 | 5.5 | Magi — 215 stars, a permissive licence, no company, and an install path that begins with building the desktop package from source. Nothing here is trying to be sold yet. |
| La Jefa | 4.5 | 5.0 | Magi — Free at sixty desks and governed nowhere: the permission layer it advertises is local to each installation, with its whole state living in a directory under each home folder. |
| El Hacker | 7.3 | 7.3 | no preference |
