GitHub Actions vs GitLab CI/CD

Q: Why do the AI models rank GitHub Actions ahead?

On best ci/cd platform for cloud-native teams, the models' verbatim reasoning: "The default CI for the majority of cloud-native teams because it lives where the code already is — massive marketplace of reusable actions, first-class container/K8s tooling (buildx, kaniko, kubectl, helm actions), OIDC federation to AWS/GCP/Azure that kills long-lived cloud secrets, and free tiers that make adoption frictionless; assumption: the typical team hosts on GitHub, which materially drives this rank."

GitHub Actions leads: the AI models rank it above its rival on 2 of 2 shared leaderboards. Based on how ChatGPT, Claude, Gemini & Grok rank both across 2 shared leaderboards — re-polled on demand, reasoning shown verbatim.
