I believe it was the inventor of Regex who said:

Easy things should be easy, and complicated things should be possible.

The problem with GCP is that a bog-standard setup is considerably more complicated than it was before. Maybe the config files are roughly the same, but there isn't a single dashboard where you can see everything from storage to instance usage to queue delays anymore. Instead there are a bunch of dashboards, each with way too much detail for getting a broad overview of your metrics.
