Pinging my existing Hetzner servers is around 45ms which is acceptable latency for me. Reliability from Hetzner hasn't been great for our servers but for what I need it for it is reliable enough.
Just remember that with the lower end dedicated servers you are dealing with desktop class hardware. With the last server I received from them one of the HD's in a raid1 was dead and although they replaced it quickly I was required to reconfigure it wasting quite a bit of time.
