Which one would each critic pick
| Critic | 99 | Continue | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 5.0 | 99 — Pick it if you hand-code in Neovim and want an agent that assists rather than takes over; pick CodeCompanion.nvim if you want the fuller editor experience. |
| El Crítico | 5.5 | 4.3 | 99 — It delegates every hard part to a provider CLI it does not control, and the README calls the project beta with an API that still changes. |
| El Profesor | 5.5 | 5.0 | 99 — Documentation is a single README, so the search and work commands are described rather than specified, and no benchmark is claimed. |
| La Inversora | 5.0 | 3.0 | 99 — 4,752 stars attached to a personal project by a well-known creator, with no company, no price and no revenue line behind it. |
| La Jefa | 4.5 | 3.0 | 99 — Zero seat cost, and zero of everything else procurement asks for: no vendor, no support, no audit trail, and the bill sits with whichever agent CLI it drives. |
| El Hacker | 7.0 | 7.3 | Continue — Read-only, but Apache-2.0 with config.yaml, Ollama and llama.cpp support intact; I can keep it alive on my box longer than the company kept it alive. |
