Which one would each critic pick
| Critic | Graphite Agent (formerly Diamond) | Greptile | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.8 | Greptile — Pick Greptile when the bugs in your pull requests come from code the diff does not show; pick CodeRabbit for more hosts and free public repos. |
| El Crítico | 6.3 | 5.5 | Graphite Agent (formerly Diamond) — The agent reviews, fixes and updates pull requests with no sandbox in the product, so a reviewer that writes code has nowhere isolated to write it. |
| El Profesor | 5.5 | 5.8 | Greptile — The whole-repository index is the correct architecture for review; whether it works is unmeasured, because 50 vendor-selected bugs is not a sample size. |
| La Inversora | 7.3 | 6.0 | Graphite Agent (formerly Diamond) — Graphite's asset is the stacking workflow and merge queue; AI review is a retention feature priced into a seat it already sells, which is where the pricing power lives. |
| La Jefa | 6.0 | 5.8 | Graphite Agent (formerly Diamond) — Sixty Team seats is $2,400 a month on annual, SSO, SAML and the SIEM audit log are Enterprise only, and AI features are off by default until an admin turns them on. |
| El Hacker | 3.0 | 3.3 | Greptile — Closed and cloud-first, with my own model endpoints buried in the Enterprise-only Compose install; the one thing I can script against is the hosted MCP server, which is at least something. |
