Do you have benchmarks on that? Not my experience for network speeds and CPU of individual machines but it's been 6 months since I checked.
Not just the performance, all Google Cloud services are fully managed (Think of S3 and Lambda on AWS). No servers! On AWS, only a couple of services are fully managed. Rest of them are a thin layer on top of EC2. If AWS is DevOps, Google Cloud is NoOps.
