my experince with GCP support during the free trial (with the advertising explictly saying that they provide "Technical Support for free trials") was:

    1. create ticket
    2. immediately receive email telling me I'm barred from free technical support and told I need to purchase a "Silver, Gold or Platinum Cloud Platform Support package"

Hah, the best part is I legitimately had to deal with GCP actually being broken (resource refused to delete) that could only be fixed by Google internally (both portal and cli returned http 500). Imagine the joy I had not having "technical support" as a benefit.

Because it's a lot cheaper than AWS, whose $500/month customer service is just as bad?

AWS support is indeed pretty crappy. $500 is not a fixed price. You pay 10% for the first 10K/month, 7% of $10K-$80K and so on. The Developer plan is 3%, but is pretty worthless - it should be renamed to rookie-plan or similar - you can get the same answers on SO for free within minutes instead of waiting days. Getting past first-level support on the Dev plan with harder technical issues takes weeks in my experience.

It takes time and energy to migrate, which is in progress
