When we first launched on GCP, there was no question that it was the way to go (frankly, because of BigQuery). Working with AWS, when we launched, was going to cost us significantly more up-front, before we had even brought on our first customer.
Fast forward 5 years... AWS has closed the gap in every way that matters. I still, frankly, trust Google's Security more than Amazon's, but I don't encourage folks to use GCP the way that I used to.
Just the opposite. In 2021, no questions asked, it's either AWS for general compute, or something more targeted if your business doesn't need it.
Until you get to the point where your bill is larger than a dozen engineering salaries, you won't get any respect from these people.
