Which one would each critic pick
| Critic | Browser Use | Claude Agent SDK | 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 | 6.5 | no preference |
| El Profesor | 6.8 | 7.0 | Claude Agent SDK — Eight documented built-in tools, subagents with their own context, hooks and resumable sessions; other languages get the same loop by shelling out to the CLI with -p and --output-format json. |
| La Inversora | 7.3 | 8.0 | Claude Agent SDK — Renaming the Claude Code SDK to the Claude Agent SDK is Anthropic saying the product is the loop, not the CLI, and the upsell above it is already named: Managed Agents. |
| La Jefa | 6.0 | 7.3 | Claude Agent SDK — As a dependency it rides the Bedrock, Vertex AI or Foundry contract we already have, costs nothing per seat, forbids consumer subscriptions, and comes with branding rules legal will want to read. |
| El Hacker | 7.8 | 5.3 | 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. |
