It really depends on what type of business you run and who will be building and maintaining the system. Azure gives the business the ability to integrate with other MS systems and has good sales teams who will hold your hand. If you are an ISV then it is not that important to you, instead you need specific SLAs, region support and an easy path for the integration. Overall nobody cares about small teams that count every penny and spend up to XXk a month on infra because they could spin up their openstack cluster at any moment and leave.
I agree there is room for improvement but your arguments are weak. The user interface (whoever is using it?) is questionable in AWS and in GCP as well, IMO it is because of the underlying complexity in all clouds. Reliability statement should be backed by the existing SLA, or is it some complaint that MS does not provide four/five 9s for every service? The bit about it being expensive depends on what you compare it with, AWS is notorious as well, every time you need something to build you do not know if that will cost 1k or 10k per month.
I am not some sort of Azure fanboi and love AWS but there are things MS is good at as well, however people hate that.
