I’m running $2500 worth of servers on Hetzner privately since 2015 and about $400 worth of VMs on Hetzner Cloud. The only instance of issues with them was Hetzner locking the outgoing traffic of a VM after it started bursting a few million packets to the local network in an infinite loop. I called them, they explained it, I fixed it and they unblocked it. Pretty happy with Hetzner. The traffic that goes over some of my servers would be $50k+ per month on AWS.
