GCP is head-and-shoulders better, at least in my not-super-involved experience (that is, I haven't automated everything). Azure has been buggy as all hell. Terrible confusing slow portal. Slow boots. Machines that hang, requiring the "Redmond shuffle" (resize a Windows VM twice to get RDP working again). Insane SSD situation.

AWS is solid but feels cluttered, I guess. GCP is just ... a breath of fresh air. And it's way cheaper than Azure (last I checked, some VMs were 1/5th the cost; our overall cost is 1/2 on GCP.)

When I did a price comparison (4 months) ago, GCP was the least expensive by a long shot.

Azure was shockingly expensive -but then again, I suspect they offer their enterprise customers discounts that may not be published.

The enterprise agreements don't help that much. Azure is banking on the fact that traditional Windows shops will pay tons to run MS's cloud. Hadoop... On Microsoft, and so on. Plus they have unique AD positioning.
