Well, you are comparing apples and oranges here. The equivalent AWS service would be EC2 and not S3. I know that you didn't start with that (as gprasanth put them in the same race), but it should be clear those two have different redundancy levels.

In fact, I don't know where AWS nor Hetzner stores the 'disk' of the VPS or even the backups. And while those are undoubtedly essential attributes for enterprise-level services, I think especially for side projects the usability of the service is quite relevant.
