Which one would each critic pick

CriticcezarHivePick
El Juez——not enough reviews
El Amigo6.86.8no preference
El Crítico5.86.0Hive — The install notes warn that pip install -e . at the repository root creates a placeholder package and Hive will not function correctly, which is a trap shipped as a footnote.
El Profesor7.37.0cezar — Runs are separated by git worktrees and every artefact is written as JSON, NDJSON and Markdown inside the repository, so the record of a session is diffable rather than queryable.
La Inversora5.86.0Hive — Aden is a Y Combinator company selling a hypervisor and secure desktops for agents, with the free runtime as the funnel and a discovery call as the price list.
La Jefa5.55.3cezar — Nothing per seat and no vendor account, but the sixty subscriptions underneath it are the real invoice, and running several at once is how that invoice grows.
El Hacker7.88.0Hive — Apache-2.0, LiteLLM underneath so a hundred providers and a local Ollama all work, and keys land in an encrypted store at ~/.hive/credentials instead of my shell history.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.

Want a third column? The compare tool handles any two agents. Three-way comparisons are on the roadmap once the spec rows are all verified.
