Which one would each critic pick
| Critic | Browser Use | Composio | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.3 | Browser Use — Pick Browser Use if you write Python and need an agent to click through a site you cannot get an API for; pick Agent TARS if the thing you need to click is not inside a browser. |
| El Crítico | 6.5 | 6.8 | Composio — It sits in the authentication path for every application it connects, so one incident there is one incident across every integration you shipped, at once. |
| El Profesor | 6.8 | 6.5 | Browser Use — Odysseys, 87.4% over 200 long-horizon tasks, is self-reported by the vendor on its own benchmark; the 98% on Online-Mind2Web is a public set, but scaffold and attempts are not stated. |
| La Inversora | 7.3 | 7.3 | no preference |
| La Jefa | 6.0 | 6.5 | Composio — There is no seat price to multiply; the meter is 100K tool calls free and $0.0003 after that, which is a forecast rather than a budget line. |
| El Hacker | 7.8 | 6.8 | Browser Use — MIT, Ollama in the provider list, provider-prefixed model ids for anything else, and Playwright underneath; the MCP server, though, lives at api.browser-use.com behind an API key, so the good part has a login. |
