As I see it, GCP has successfully become a peer competitor to AWS and Azure (which I was, to be honest, uncertain they could pull off), while, conversely, Workspace is a truly painful experience compared to almost every alternative -- and I'm including Sharepoint in that. It's horribly disjointed, and they've changed chat and conferencing solutions so many times that it's virtually impossible to figure out how to make their own hardware work with their own services. O365 has its issues, but it hangs together as a single product far more successfully than the farrago Google is pushing.
