Docsis 3 cable modem for comcast xfinity

Looking to purchase docsis 3.0 cable modem to leverage the faster speeds allowed by the new comcast xfinity. Any suggestions on which one of the "approved" modems would be best? I'm an online gamer (PC/Xbox), do work from the home, use netflix, download quite a bit, etc.

Want to get something that has been tried and true and is designed for an enthusiast. Any suggestions?

I noticed there are only 3 that are ipv6 compatible. I know ipv6 hasn't been widely implemented, but I'd rather get the compatibility now and be prepared for it.
