“Its own showcase hands it a $5,000 budget and a Ritz-Carlton booking, which is one way to find out whether an agent stops.”

“Billed as a personal agent that does live web research, which is the most expensive way yet devised to open a browser tab.”

Which one would each critic pick
| Critic | Agent TARS | Agenvoy | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.0 | Agent TARS — Pick Agent TARS if the thing you need automated has no API and lives in a desktop app; pick Browser Use if it lives in a tab and you write Python. |
| El Crítico | 5.5 | 5.3 | Agent TARS — The README's newest entry is dated 2025-11-05 and the quick start still pins claude-3-7-sonnet-latest; two products share one repository and the cadence has slowed to a stop. |
| El Profesor | 6.0 | 5.5 | Agent TARS — The kernel is MCP, context is a protocol-driven event stream, and grounding is visual, DOM or hybrid; the model is the UI-TARS work in arXiv 2501.12326, whose numbers the README does not restate. |
| La Inversora | 5.3 | 5.5 | Agenvoy — 481 stars, a product domain and a single open binary with nothing to sell beside it: the company is a name on a website, not a cap table. |
| La Jefa | 5.0 | 5.3 | Agenvoy — The only documented install is a script piped into a shell from a vendor domain, which is where sixty seats and my security questionnaire part company. |
| El Hacker | 7.0 | 7.0 | no preference |
