Azure web ui developers are actually proud of their claim that it is in their opinion the largest SPA in the world.
If that is your comparison then AWS Console is amazing.
In general tho, AWS Console is OK at best, it does the job and for some services it is actually good. Many services are awful tho.
OMG, as bad as the AWS console is, Azure is much worse. The convoluted interface is bad enough, but the SPA warts make it even worse. Not supporting basic browser functionality like tabs is awful.
Surely the console is only for experimentation and checking on things? I figured anything proper should be done in a reproducible way (IaaC like Terraform/CDK/CF)
IMO it's a better UI than O365/Azure and I don't have much experience with Gcloud to say much but they seem about equal but still leaning towards AWS as the best UI of the top 3 cloud providers.
