In general Gitlab is the most feature rich and most flexible currently, so I'd label it as the best.
However usually the best choice for a given project is what integrates the easiest with other services. So for example if your deploying on GCP, Cloud Build is the best simply because you have to work less to integrate it with the rest of GCP. It does lack more features then gitlab, but most of the time CI/CD just needs to be easy to use since its more of a "get it working and forget" type of utility rather then one that requires more and more capabilities.
