The way that gitlab shines is just fundamentally better than GitHub actions.

It's really easy to extend and compose jobs, so it's simple to unit test your pipeline: https://gitlab.com/nunet/test-suite/-/tree/main/cicd/tests?r...

This way I can code my pipeline and use the same infrastructure to isolate groups of jobs that compose a relevant functionality and test it in isolation to the rest of the pipeline.

I just wish components didn't have such a rigid opinion on folder structure, because they are really powerful, but you have to adopt gitlab prescription
