Azure DevOps is the gold standard for Pipelines.
Really?
I grant you pipelines are the best bit about ado, but the fact that you can’t test them is a pain.
And the webhooks and templating are pretty messy and unpleasant quickly.
We’re changing from ADO to GitHub (had to be an MS product for corporate) and the infra people are looking forward to GHA as they prefer their maintenance to ADO pipelines.
AD is just sourcesafe/tfs/vsts with rebranding, each time trying to get rid of the bad reputation in developer circles.

That's not saying much, since it's still dependent upon the untyped mess that is YAML.
