Not OP, but want to chime in.
My experience with Azure support has been dreadful, to say the least. Insanely long response times, being bounced from agent to agent, people just misreading the ticket. I really don't want to deal with Azure at this point because I don't trust the support.
Most of our company infra is on AWS, and while they aren't without fault, I can say that every time we needed to talk to a human being from their side, it was quick and on-point.
