Title should maybe be switched to "Google Cloud vs AWS Onboarding Comparison for YC companies". Not to say that isn't a useful article on its own, but it's hard to draw too many meaningful conclusions for the rest of us when the first line of the AWS bullet points is "reach out to dedicated YC email".
This is also pretty specific about needing more free credits than GCP provides out of the box. If you just want to get started with GCP, you just sign in with your Google Account for $300 in credit. When you run out you can just start paying with a credit card.
AWS: makes me apply to a program to get credits and if I want to price out anything it's almost a full-blown research effort where I have to dig through documents and cross reference tables between different services and I still probably miss something important. Free tier is opaque enough to frustrate even "use it at small scale and see," because you still have to do the research to see if they are pulling a "your first hit is free but try to scale and WHAM." Oh, but they're customer obsessed, so after much begging and pleading they'll refund half of WHAM, one time.
