Which one would each critic pick
| Critic | Swarms | Upsonic | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.0 | Swarms — Pick Swarms if you want to try several orchestration shapes against the same task by changing one argument; pick AutoGen for a more settled community around the same territory. |
| El Crítico | 5.5 | 5.8 | Upsonic — The stated safety model is a workspace path plus blocked dangerous commands, and a command blocklist is the weakest control in this category, not a sandbox. |
| El Profesor | 5.5 | 6.3 | Upsonic — Prebuilt agents are packaged as a skill, a system prompt and a first message, which makes a published agent a reproducible artifact rather than a description of one. |
| La Inversora | 5.0 | 5.5 | Upsonic — A company name, a documentation site and no price anywhere, which means the product decision has not been made yet and the framework is holding the position. |
| La Jefa | 5.3 | 4.8 | Swarms — The cost is not the licence, it is a mid-level engineer choosing correctly among a dozen orchestration structures with no measurements to choose by. |
| El Hacker | 6.8 | 6.5 | Swarms — Apache-2.0, an agent becomes tool-enabled by setting a server URL and discovering what is there, a public server works with no configuration, and a guide file ships for coding assistants. |
