With hetzner you find it nice until your first hardware failure occurs, which could take 3 days to get solved, then you come back to a VPS provider where you can destroy/create instances in a heartbeat. If you run a low traffic/profitless blog hetzner & co might be fine for you, for mission critical stuff I want flexibility.

Flexibility in my case. I can go from one server with 8GB of RAM to 8 copies of that server with 32GB of RAM each and back again at the press of a button as and when the need arises.
