Not GP, but GCP's GUI is incredibly confusing and difficult to use. It is clearly a variety of products (poorly) stitched together. That has nothing to do with Compute Engine, and AWS is just as bad (if not worse).

My new projects will all be on Azure because Microsoft has pivoted to a company with reliable investment in UI, developer-friendliness, and long-term support. Serving businesses has also been a core of their company from the beginning, whereas Google seems unwilling to provide the human support required and AWS is clearly at odds with Amazon's primary culture.

It does seem like the underlying products in GCP are very good, but they mostly seem to replicate other offerings from Azure and AWS.
