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.

I've looked into it, too, but I couldn't get myself to get a server there. Their DDoS protection really isn't that good sadly.
