Which one would each critic pick
| Critic | Supermaven | Twinny | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 3.3 | 3.8 | Twinny — Do not adopt this. The project site itself says it is archived and the authors have moved to a successor, so pick Tabby for local completions with a future. |
| El Crítico | 2.8 | 3.5 | Twinny — An unmaintained editor extension is a dependency on a moving host: the editor API keeps changing underneath, and nobody is left to follow it. |
| El Profesor | 4.0 | 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 | 2.3 | 3.0 | Twinny — There was never a company, and the maintainers explicitly moved to a successor project, so whatever value existed has already been transferred out of this asset. |
| La Jefa | 1.8 | 3.0 | Twinny — I cannot roll out something the publisher has declared finished, and there is no support channel, no maintenance and no security contact behind it. |
| El Hacker | 2.3 | 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. |
