My experience with Azure match Google's reputation, and no, having an Enterprise Agreement with Azure doesn't help one bit, other than having an army of evangelists and partners chasing after you.
I completely disregard any documentation or information older than 2019, and I'm a bit suspicious if it is from the first half of the year, that is how often they change things for no apparent reason.
Their support will likely try to convince you to rewrite your app with their latest stack than solve obvious issues with Azure.
The only positive thing about the whole ecosystem is that support and evangelists/presales will likely admit bugs and share workarounds they've used. For example deploying AKS from the portal has a 50% chance of failing because it will not have created the service principle before something else requires it - so they will recommend creating the service principal in advance and selecting it in the config.
