On an ability to plug things in and get things working Azure still wins. I would stick to AWS or Azure.
I get the feeling Google is only offering the same as its in house services to the public so they can get free troubleshooting/bug fixing and stop their support staff from growing complacent.
I know that Google as a whole has a rep for support which isn't great. However, I also know that Cloud is trying really hard to show that isn't the case with Cloud products (as is the company as a whole, my personal experience with support phone lines at Google Play, for example, have been really good). We have Stack Overflow (which we as devs check in on to see if there are problems we can help with e.g. [1]), we have support packages which have real live human beings on the other end [2].
I know everyone here in my dev team is 110% behind support being great, but it's one of those things where we'll be judged by execution rather than words (as it should be).

It seems a waste of talent to have developers picking up the phone when I call developer support, but it would be nice if that team could run stuff by developers when they need to. They also need better training on typical things that developers might call about. (Eg. "Sandbox seems to be down, can you confirm and provide an ETA on the fix?")
