GCP has the superior UI, api and design. I prefer it over the other clouds: Azure plain sucks and AWS has too much bloat and does IAM/accounts worse.

In my experience GCP's core services are very stable: I had a site running on free tier App Engine for over 10 years without any supervision.

However it is clear that many GCP products are run by skeleton crews and will not improve. Documentation is also lacking sometimes.

Dataform for example is conceptually a great tool, but hampered by really basic UI bugs.

I found Datastream (change data capture tool) impossible to use. You would think that shoveling data between 2 GCP products (Postgres and BigQuery) would be easy, but I spend a week fiddling with obscure network settings before giving up.
