Share codes and packages across the whole organization. We have developers most of the time work from home or overseas like in India. We can test and deploy the package when they deploy the new changes into the Azure Artifacts. Azure Artifact can promote our package to the correct system like DEV, UAT, or Production. It also provides retention policies to automatically clean up expired packages.
RubyGems is a great packaging library primarily because of its verbose logging information and easy to navigate system architecture. We've dealt with artifactory systems in the past for Java and JavaScript, and RubyGems just makes it a lot easier to handle the packaging and deployment of our reusable libraries. We've noticed in the past that there are times where (if all 200+ teams) are releasing at a similar time that publishing the gems can lag, but that's fairly rare.
RubyGems has strong community support and finding issues to errors is as simple as searching for the error message you're receiving (but usually the error is clear enough without having to bother with that). Honestly, the framework is simple enough that support isn't needed much, but it has been helpful to us in the past when we have needed it.
Azure Artifact is based on GitHub which is the best artifact at all times. Helm is open source and we may have security concerns. Crucible is a good tool but does not of a lot of support. I prefer that Azure Artifact is a solid product and with a good gene from the GitHub codebase.
RubyGems is easier to use and to troubleshoot issues overall. Sometimes when troubleshooting in other systems errors are masked and it takes a trained eye or a lot of time searching through Google trying to find out what it really means. RubyGems is very verbose and allows for quick troubleshooting of any deployment problems.
