It can really depend. I know a lot of stories of AWS support being stellar while google was bad (even discounting support for non-GCP stuff from the list). But

It can really depend. I know a lot of stories of AWS support being stellar while google was bad (even discounting support for non-GCP stuff from the list). But at the same time I can refer to enterprise-tier support at AWS, which has gone past ticket stage into "regular calls with AWS support engineers to help architect our solution" and certain critical topics ended up ghosted (my first reaction was that support had no idea about the functionality we asked about, later experienced taught me that at best, the AWS documentation lied by omission. At worst it was divorced from reality.)
