Personally, I find AWS's pricing complicated, and there are so many different services that it's confusing. I think it's mostly a UX issue, but it's really overwhelming.

DO, Lonnie Linode, and Vultr are very simple, so that's what I use. Perhaps if I start needing more from my hosting I'll look at AWS, but it's just not worth my time to figure it out for the scale of projects I'm doing.

AWS just seems too complicated to me. I like to spin up simple VMs (with local storage) without any surprises.

For one thing you have no fixed monthly cost on AWS
