In fairness I have only tried Jenkins, CruiseControl and Azure DevOps. What sets TeamCity apart is the use of Kotlin. You do have to invest a fair amount of time to get the most of it, but when you do the return is great.

Putting together a pipeline in Azure DevOps with tons of YAML is not a great experience.

As far as Jenkins is concerned I think that it's biggest selling point is that it's free.
