Which one would each critic pick
| Critic | Charlie | Traycer | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.8 | Traycer — Pick this if planning is where your agent sessions go wrong; pick a plan mode inside the agent you already use if you would rather not add another window. |
| El Crítico | 5.8 | 5.8 | no preference |
| El Profesor | 5.8 | 6.8 | Traycer — Handoffs carry a shared filesystem, artifacts and history, which addresses the specific failure of multi-agent designs: intent that survives only as a summary. |
| La Inversora | 6.8 | 6.5 | Charlie — A ladder from $50 to $200 to $1,000 a month, buying two and a half, ten and fifty times the free limits, is a well-built meter on a process that never idles. |
| La Jefa | 6.3 | 5.5 | Charlie — Plans meter a workspace rather than a seat, so sixty engineers do not multiply the bill, and every tier carries prepaid overage on top of the plan. |
| El Hacker | 4.0 | 5.5 | Traycer — Closed source and no MCP client, so there is nothing to read and nothing to attach — but local agent runtimes and custom agents are both supported execution targets. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
