I have a hard time using any of google's stuff - cloud, whatever. Have had to deal with 'google search console' recently. "Give us your sitemap!". OK... "Could not fetch". The explanation for "could not fetch" might be "couldn't fetch" or "hasn't fetched yet" or "read but not processed" or "error reading" or.. anything else. On March 9, I had a sitemap entry listed as "couldn't fetch" updated to "last fetched date" of March 10 (9am UTC-4, so not even close to march 10 UTC time). It's just.... buggy. Colleagues currently moving stuff to google cloud (by edict of cto) are encountering bug after bug after slowness after flakiness. Google "support", to the extent they answer, says "we don't know".
Might it have been 'technically better' on day one? perhaps. But if it's buggy/flaky to deal with, and they have no support, not sure how you'd even verify the "technically better" part. How would you trust any numbers you see reported in their own tools?
Had to use GCP stuff about 6 years ago. It was flaky/slow and relatively unsupported then. Watching colleagues go through stuff today, in 2023, it seems no better.
