Which one would each critic pick
| Critic | Agents-Flex | Solon AI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | Agents-Flex — Pick Agents-Flex if you build on the JVM and do not want Spring Boot as the price of admission; pick Spring AI if your shop already runs Spring and wants the safer bet. |
| El Crítico | 6.3 | 6.0 | Agents-Flex — One project carries agents, RAG, Text2SQL, web search, speech synthesis and image generation. Each is a maintenance surface, and none of them is versioned separately. |
| El Profesor | 7.3 | 7.5 | Solon AI — Instructions and toolsets are activated conditionally rather than always present, which makes the prompt a function of the situation instead of an accumulating constant. |
| La Inversora | 6.8 | 6.8 | no preference |
| La Jefa | 6.5 | 7.0 | Solon AI — Nothing to license, and it drops into the application servers my teams already deploy, which means no new runtime, no new container image and no new deployment pipeline. |
| El Hacker | 7.8 | 8.0 | Solon AI — Apache-2.0, and it is both an MCP client and an MCP server, with a built-in dialect that points at a local runtime, so the whole thing runs against weights on my own box. |
