“It renamed itself away from the product it wraps to signal support for other providers, which is optimism filed as a release note.”

Which one would each critic pick
| Critic | AionUi | Swttch | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.8 | no preference |
| El Crítico | 6.0 | 6.0 | no preference |
| El Profesor | 6.0 | 6.5 | Swttch — It takes the vendor's own editor extension as its baseline and states that no credential source is scanned silently, which is a provenance claim and a negative claim in one sentence. |
| La Inversora | 5.3 | 5.5 | Swttch — 99 stars, one author, and a product whose entire surface is one vendor's command line. The rename toward a neutral name is a hedge against exactly that. |
| La Jefa | 5.3 | 5.3 | no preference |
| El Hacker | 6.8 | 6.3 | AionUi — Apache-2.0 across two repos, Electron in one and a Rust engine in AionCore, assistants defined in a JSON catalog, Ollama and LM Studio through a Custom platform, and MCP transports injected per agent. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
