Which one would each critic pick
| Critic | Cline | Junie | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.0 | Cline — The open editor agent to pick if you want to approve every action and choose your own model; slower than the closed tools, and yours. |
| El Crítico | 6.5 | 6.3 | Cline — Approvals slow it down by design, the bill scales with how much it reads, and there is no sandbox behind the approve button. |
| El Profesor | 6.3 | 7.0 | Junie — Junie's SWE-rebench first place is a rolling-set result that moves run to run by the organizer's own account, and its debugger integration is a verification channel most agents on this board lack. |
| La Inversora | 5.8 | 8.0 | Junie — JetBrains sells IDE renewals, and Junie is a retention feature priced through AI plans, which means the agent does not need to win, it needs to be good enough that nobody leaves. |
| La Jefa | 5.8 | 7.5 | Junie — Pooled credits through JetBrains Central, admin-set spending limits, and an Enterprise AI plan at $60 a user on IDE licenses we already hold; approved with conditions until the burn rate is measured. |
| El Hacker | 9.0 | 6.0 | Cline — Apache-2.0, every prompt readable, any OpenAI-compatible endpoint including my local box, MCP from a JSON file; this is what ownership looks like. |
