GitHub Actions
My default recommendation is GitHub Actions if your code already lives on GitHub; I would not run a lengthy platform selection unless you have unusual scale, isolation, compliance, or deployment-governance requirements.

GitLab CI/CD
GitLab CI/CD — Choose this first if you use GitLab or want a tightly integrated DevSecOps suite, with pipeline-as-code, runners, merge-request pipelines, monorepo-friendly parent/child pipelines, and self-managed options.

Across the 1 category GitHub Actions and GitLab CI/CD both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks GitHub Actions ahead at least as often as not, with Gemini the most lopsided.
