I agree. If I want to set up something at Digital Ocean, I can know the costs without any complex algebra or a specialized calculator like AWS and Azure have.
Obviously DO has a lot less features than AWS or Azure, but they do add features every couple of years, and their interface is so much simpler to navigate.
I feel DO/Linode/etc are more closely related to a hosted vSphere + f5, than a "cloud provider" in the same vein as AWS/Azure.
Having used both daily for years now I can certainly see why DO will have an appeal to some over something as large as AWS.
It is way less confusing and their docs are much easier to get through. I always recommend people starting out with cloud VMs to go DO instead of AWS
