Not directly a response to you, but GCP is actually phenomenal in some areas over AWS: BigQuery, Data Studio (I know it's not really "GCP" but vs AWS' offering), and Pubsub come to mind.
Oddly enough, they falter in other areas: no equivalent to Kinesis Firehose, and true to your point, I was told by customer service just to build my own DataFlow job to take a Pubsub topic and make files.
It's like some of their product managers have a very customer-first mindset (BigQuery, Pubsub) and some could not care less.
