GitHub vs Azure DevOps

Our Software Engineering team is currently working with Azure DevOps, and are considering a migration to GitHub. We are looking at how to motivate the benefits of GitHub compared to Azure DevOps. We have identified ease of integration as one of the things that GitHub does very well and security scanning of code repositories. Is there any material that can be shared with me and my team to help build the case for migrating from Azure DevOps to GitHub? Thanks!
