Maybe this is preference or something changed since I used GCE daily, but I disagree on almost all these points.
* Documentation - On the surface, GCE docs always looked better to me until I realized how many mistakes there were and things out-of-date. Not to mention there was too much of the obvious documentation and not anything regarding subjects where I'd actually want detailed docs. Although Amazon's docs are trash, they have the benefit of everyone and their mother writing about how to do x, y, or z. Whether that's a benefit or not, it depends on the author.
* Console - The console was sometimes more responsive depending on the action, but for some things was worse. Overall I'd give this one to GCE as well, but I think the GUI was a mess in places. Perhaps that's more based on my total usage of Google Services, which are a superset of GCE. Regarding command line tools though, I felt these were awful, slow, poorly documented, and buggy. Again, maybe an update fixed some of this. Google has a really bad history with consoles. Amazon's GUI is 90sish at times, but it's been pretty good to me and the API just works.
* The answer to this one is really it depends on the machines, location, etc. GCE has some advantages here that are well documented, but performance of a running machine was never really a problem I faced on Amazon provided you select a good instance type.
* Can't argue here. Amazon does like to give out its share of freebies though if you are a big enough customer or paying attention to the community.
