Each has their trade offs. AWS absolutely has a high premium but Hetzner has some quirks.

Recently we had several of our VMs offline because they apparently have these large volume storage pools they were upgrading and suddenly disks died in two large pools. It took them 3 days to resolve.

Hetzner has no integrated option to backup volumes and its roll your own :/ You also can't control volume distribution on their storage nodes for redundancy.
