You can ask 100 people and they'll all give you a different list. It's subjective.
I think a less personal ranking would be, as a business owner, which of those providers is more dependable? As in, you don't care about evil, just your stuff working. I think maybe OpenAI?

True. With 5 choices you need at least 126 people before you can guarantee that two lists are the same.
Google. They have experience operating at scale, and AI is a big enough focus that they won't wind it down. All the big providers are kinda crappy, but if you want reliability, Google is the best option.
