Which one would each critic pick
| Critic | Neo | pi | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.5 | pi — Pick pi if you want a terminal agent small enough to read in an afternoon and extend in TypeScript; pick OpenCode if your workflow already depends on MCP servers. |
| El Crítico | 6.8 | 6.8 | no preference |
| El Profesor | 7.5 | 7.3 | Neo — One coordinator delegates bounded work and independent read, search and inspection subagents run in parallel, which separates gathering from mutation at the process level. |
| La Inversora | 6.0 | 5.5 | Neo — A hundred and twenty-nine stars against two hundred and fifty forum mentions in a year is unusual: the conversation about this is larger than its adoption. |
| La Jefa | 5.8 | 5.5 | Neo — Nothing per seat for sixty engineers, sessions stay local with no plugin stack to review, and there is nothing that runs without a person, so it never enters delivery reporting. |
| El Hacker | 7.0 | 8.5 | pi — MIT TypeScript, extensions that add tools, commands and UI, /llama for llama.cpp on my box, ANTHROPIC_API_KEY in the environment, and packages to share it all. |
