I don't think this holds true anymore. It takes Apple some time to get their cloud offerings right, but eventually they do. iCloud works pretty good these days. iCloud photos is pretty slick and just works.
Does it go down once in a while? Yeah, but so does GCP every now and then.
Apple is a hardware company, Google is a cloud software company. They do cross over (iCloud, Pixel), but I doubt they'll ever match each other in terms of their respective domains.
Google isn’t a very good software company. They kill off anything we like. Makes it difficult to buy into the Google ecosystem when you’re not sure if it will exist in a couple of years time. Other than Gmail and Google Search. Just too risky. I wouldn’t even touch GCE.
Edit: not a dig at engineers at Google who are crazy talented. In reference to Google as a company killing everything off.
They should hire more people who actually understand how server infrastructure works. A healthy head is little comfort if the rest of the body is sick.
Apple is not very good at its cloud offerings. Never had been.
