EC2 on-demand/hourly to Hetzner monthly pricing is not really an apples-to-apples comparison. EC2 reserve pricing is more similar and about 1/2 or less of on-demand fees. Hetzner is still cheaper, and if all you need is a low cost dedicated server w/local disks and bandwidth, this is a great choice - but AWS provides an entire ecosystem of services including configurable EBS and S3 storage, as well as more diverse and scalable purchase/provisioning options.
