Which one would each critic pick
| Critic | CodeCompanion.nvim | ECA | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.8 | 7.3 | CodeCompanion.nvim — Pick it if you want one plugin covering chat, refactors and driving an external agent; pick avante.nvim when inline suggestion and instant application are the whole job. |
| El Crítico | 7.0 | 6.5 | CodeCompanion.nvim — One maintainer is shipping a chat client, an inline transformer, a workflow engine and an external-agent host in the same tree, and surface area is the risk. |
| El Profesor | 7.3 | 7.8 | ECA — Tool and prompt metrics are exported over OpenTelemetry, which makes this one of the few projects here where a user can measure the assistant instead of describing it. |
| La Inversora | 6.0 | 6.3 | ECA — 983 stars, a permissive licence, no company and a Clojure codebase, which narrows the pool of people who could pick it up if the current maintainers stop. |
| La Jefa | 6.5 | 7.3 | ECA — Zero licence cost across sixty desks, and settings are defined once globally or per project, which is the closest thing to central policy anyone in this category offers. |
| El Hacker | 9.0 | 8.5 | CodeCompanion.nvim — Apache-2.0, a first-class local adapter plus custom adapters for any compatible endpoint, and a tool-protocol client, all configured from a Lua table I keep in git. |
