Hetzner.
Simple, efficient, no useless fluff, decent prices for a good service, no hidden surprises or overcomplicated setups.
What more could you ask for?

I'm a Hetzner customer, too, I fucking love them.

The service and support is just awesome. They replaced a broken hdd in my server in a matter of an hour.

And they got some kind of market for "used" servers, where you can be lucky and get true beasts of servers for 30 euros per month.
