I generally go with the known ones, the things I search for are generally the privacy statements and the pricing handling clearness.<p>For example, I needed an object storage publicly accessible over HTTP, so I looked into Amazon S3, which I didn't even bother trying, because apart from the fact that their docs are very poorly written, the pricings pages are a huge mess and I still haven't managed to see what were the real costs, and how they were handled.<p>While disliking Microsoft, I decided to try Azure, for their blob storage, and not only the privacy statements were way easier to reach, the pricings page was really clear and easy to understand. Furthermore, their administration panel is nicely done, unlike AWS.
