What's Your Experience with AlloyDB?

Hey everyone! We have been trying out AlloyDB in our (write heavy) use-case for about 2 months now. And I wanted to ask you for your experience with it. I am asking because our experience has been horrible.

  No independent scaling of CPU and Memory
  No public IPs
  No non-ha version available
  No stopping of the instance possible
  Performance, actually worse than CloudSQL (write heave use-case)

We moved to AlloyDB because we had good experience with Aurora and like the promise of serverless Postgres, as well as it being free initially. But since 2023 they have been charging for it, we immediately moved back to CloudSQL and cut or cost by 10x.

What has your experience been, did someone try it ? I know that supposedly they have some big increases in some read warehousy use-cases.
