“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.”

“It calls itself a sovereign agent, which is a great deal of constitutional language for a binary living in your home directory.”

Which one would each critic pick
| Critic | Agent TARS | Wizard | 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 | 4.8 | 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 | 6.3 | Wizard — Memory is stored as markdown and sessions as line-delimited records, which makes the accumulated context a document a person can read and correct. |
| La Inversora | 5.3 | 5.0 | Agent TARS — A ByteDance research project: no pricing, free remote operators, weights on Hugging Face and ModelScope, and the business is Doubao tokens on Volcengine; strategic projects get shelved, not sold. |
| La Jefa | 5.0 | 4.0 | Agent TARS — Free, no SSO or audit trail anywhere, macOS and Windows only, so it cannot run on the Linux CI fleet, and support is a Discord server; a research release, not a vendor. |
| El Hacker | 7.0 | 8.0 | Wizard — Apache-2.0, and choosing Local on first run has it size a Qwen 3 build to my hardware and start llama.cpp itself, with no key and no account anywhere. |
