Whether one is better than the other depends a lot on your individual use case and preferences.
Both types of storage have their strong suits. BackBlaze is great if you need an S3-compatible storage option that won't "max out" at any particular storage limit. The Hetzner option will be great if you want to be able to tinker around with a Linux instance and not pay for egress bandwidth.
If you're dealing with an amount of data that is consistently at the 100GB and don't have a large amount of egress, BackBlaze is the cheaper option. If you are storing closer to 1TB and do a fair amount of egress, the Hetzner option will be cheaper.
