Which one would each critic pick
| Critic | Sweep | Twinny | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.0 | 3.8 | Sweep — Pick Sweep if you live in IntelliJ or PyCharm and want fast next-edit autocomplete; pick Junie if you want JetBrains' own agent in the same editor. |
| El Crítico | 4.5 | 3.5 | Sweep — The open-source GitHub bot Sweep was known for is gone; what is sold is a JetBrains plugin on proprietary models with no terminal, no git operations and no model choice. |
| El Profesor | 4.5 | 4.8 | Twinny — Fill-in-the-middle completion paired with workspace embeddings built locally for chat context, a design predating tool use, which is why it suggests and never acts. |
| La Inversora | 4.0 | 3.0 | Sweep — Sweep is the open-source-without-a-business-model story that found one by pivoting into a niche, and the niche's landlord, JetBrains, now sells its own agent. |
| La Jefa | 4.0 | 3.0 | Sweep — No enterprise tier, no SSO, no self-hosted option and no CI mode on the pricing page, from a vendor that has already changed products once; not yet. |
| El Hacker | 3.0 | 5.8 | Twinny — MIT and small, with any OpenAI-compatible endpoint including my own, which makes it the best kind of archived code: something I can fork rather than mourn. |
