I work in the European public sector, I can name you a few reasons to pick Azure over AWS. None of them are technical though, so you certainly have a point.
Microsoft is just better at selling the whole package to enterprise where your primary function isn’t tech.
They were first to incorporate EU legislation, and are frankly still the only of the three big cloud suppliers that can show us exactly where our data has been or passed through at any time.
Their support is also excellent. We pay Microsoft a lot of money, much more than the cost of Azure because of licensing, but with it comes support. If something breaks down, I can call Seattle directly after which we will receive hourly updates by phone until the matter is resolved.
With google you get to fill a form or chat with a bot. AWS is better, but again mostly to their big customers, and since we aren’t buying office 365 or licenses from them, we’re just not big enough to qualify for the support we need.
I'd personally trade my first born with no second thoughts to use AWS instead.
