Stackdriver is priced competitively and integrates very well with Google Cloud resources. It has a free uptime check tool which is nice (but not always reliable). Review collected by and hosted on G2.com.
It is severely lacking in features and feels like a rudimentary beta product. We get what we pay for.
Also the UI is full of annoying bugs (e.g. when I mouse over dashboard settings the menu renders behind the dashboard, and once something breaks everything else on the page freezes and I have to reload often) - I hope Google fixes this soon.
I ended up moving to Datadog but continue to use Stackdriver for some less important GCP metrics that I can't export (without paying for the export, that is, since Datadog's GCP Integration calls to Google Cloud cost $$) Review collected by and hosted on G2.com.
