I don't recommend them. We used to host an online text game there (MUD) and when one of the players decided to DDOS it, Hetzner just pulled the plug. I moved to soyoustart.com (it's OVH brand) - in following month they sent a couple emails about the server being attacked and that they're trying to mitigate the attack, but game kept working.
Yes they are quick to just drop all traffic to hosts being attacked, that should be noted. Ovh is putting in a little more effort but will also nullroute your IP if it's getting too bad. Generally the hetzner network seemed more stable and less congested to me though.
