Pretty happy for my use cases. Stackdriver is no more and now fully integrated into Cloud Console. Error Reporting is useful for production errors, even on frontend. Monitoring uptime is quick and easy. Metrics alerting has been okay. Mobile app alerts via GCP app.
Cool. Like you said, having everything under one umbrella is very nice. It's a big reason why I stuck with it for so long. Ultimately, it just didn't fit well enough for my use cases.
