(Although they keep fiddling with the title, it should just be "Google Cloud Incident", it affected a lot of services)
Anyway, I've never used GCE or Azure, but plenty of AWS ;) From my experience, Amazon tends to 'forget' about issues quite quickly. Last month there was a DNS issue, ~12 hours after it was 'resolved' according to their status page I was still having issues for instance.
That being said, I have not had any full outages or downtime due to AWS issues in 4 or 5 years.
Google's network is spanning the globe. Configuration changes are more likely to affect all regions. Google is also better at reporting errors.
This is based on my own experience. YMMV
