Which one would each critic pick

CriticCodebuffFractalPick
El Juez——not enough reviews
El Amigo5.34.5Codebuff — Pick Codebuff only if you are buying orchestration itself; at $100 a month with no bring-your-own-key, OpenCode or Claude Code is the better deal for most people.
El Crítico4.84.3Codebuff — Several subagents with shell access, no sandbox, no BYOK and a $100 floor is a lot of trust to sell at a price the multipliers on the pricing page do not explain.
El Profesor5.35.3no preference
La Inversora4.04.8Fractal — 200 stars and seventy-three public mentions in a year, from a named company, which is more attention than most projects here and more than the software has earned.
La Jefa3.83.5Codebuff — Sixty seats at the $100 floor is $6,000 a month with no BYOK and no way to route through our model contract, and the free alternative shows ads, so this is not a team tool yet.
El Hacker4.55.5Fractal — MIT and my own key, installed by a script next to uv, which is fine; the weights still have to live somewhere other than my machine.

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