As another datapoint of one, I've been working with Azure for years, and have never found the UI to be unreliable.
I could go on and on. It's not like Azure is completely bad, but I far prefer the developer experience of AWS. It's not perfect, but IMO it's much better.
Regarding copying stuff, if you hover over just about any text element, a little 'copy' icon will appear. I like this feature.
Think I didn't try that? Doesn't work on CosmosDB databases. Yes, for a lot of items it's true that "copy" is easy.... but when it's not easy, it's crazy hard.
I'm guessing that your company doesn't have hundreds of Azure subscriptions (and the proportional number of other resources to manage, in them). When there are a lot of elements that you need to manage/ browse through/ look for, you start to appreciate the simplicity of the AWS ui, and the fact that it prioritizes "snappy" over "fancy".
Azure might be great for an SMB, but I think for large enterprises, AWS is still unchallenged.
Just about everywhere I'd want to filter stuff in the Azure portal, there's a search box or/and filters. Honestly, I find it to be really snappy for me.
Worst thing about it is that I was originally impressed with Azure DevOps - the onboarding was awesome, almost combined the best bits of GitLab / GitHub with none of the crap of Jenkins. It was only after going back a couple of days later it let me down.
Azure Devops is awesome though. Told my wife i'd found a modern Microsoft product I really liked, she nearly fainted.
AWS portal is bizarre, it's like each portion is written by a different company. In ECR for example, clicking into a repo is fine, but then going back doesn't do anything. Why? Even simple favicons don't look like they're from the same company. When you've got 40 tabs open you want an idea that that particular tab is from AWS or not.
Azure is nicer, but it's not reliable (see my other post on this thread). It's almost like Azure have done too much lazy-loading which persists through login sessions, you can't rely on a refresh to give you the truth - for all the problems with AWS, you can.
And yes I know this isn't CLI stuff, but it's important. Even on fully automated / scripted deployments it's sometimes nice to go into the UI and see what's going on. If it doesn't represent reality, there is a problem.
FWIW GC doesn't have any of these problems, but it is slow.
