Jenkins to me is great for prototyping certain process activities in a very arbitrary set of conventions, but it provides a lesson as to why the Java world moved on from tools like Apache Ant (XML-based Make) to Maven (convention over configuration as a tooling value). While 10 years ago such processes were not really standardized nowadays people are used to conventions like GitOps with well documented processes for how artifacts are built, deployed, and operated with container primitives after we've spent a _lot_ of time now trying to manage Jenkins installations that become incredibly brittle over time and become more of a liability than a force multiplier for the organization. So people are adopting more specialized tooling instead of trying to have Jenkins do everything under the sun from building artifacts to deploying them to deploying infrastructure with CD conventions.

Things I've found better than Jenkins once an organization lets go of over-engineered processes:

- TeamCity - Concourse CI - Circle CI - ArgoCD - Tekton

For Windows build agents I've met plenty of people successful with Octopus Deploy that have hated Jenkins and your data point is the first I've seen that went back to Jenkins.

Perhaps it's worth looking at Team Foundation Server / Azure DevOps?
