Which one would each critic pick
| Critic | Browser Use | Cua | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 7.0 | 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 | 6.8 | no preference |
| La Inversora | 7.3 | 6.3 | Browser Use — Zurich and San Francisco, an own model line priced at $0.24 per million input tokens, and browsers at two cents an hour: the margin moved from renting Chrome to selling inference. |
| La Jefa | 6.0 | 6.0 | no preference |
| El Hacker | 7.8 | 8.5 | Cua — MIT, pip install cua, a driver install script, an MCP server so my own client can drive a desktop, and QEMU or Apple Virtualization locally with no cloud account. |
