I've spent a good bit of time with both now. GCP has some real potential but AWS support is nothing short of fantastic. I leaned on them multiple times and had people actively working with me on the phone to get problems solved, following up with me, etc.

I was impressed.

Just got on the Silver plan with Google and only had one support ticket so far, but they got it resolved. Haven't really needed to push it yet, but we will see what happens.
