Hamilton is the more talented of the two, though Rosberg could win the WDC if "reliability/circumstances" go in his favour, like they did early in the season. Don't give much chances for it to happen though. Back in 2014 at the same time Rosberg's points situation was even better than now (leading by 29 pts after Spa), yet couldn't win it.

Much is discussed about Mercedes' reliability, but they haven't had a car-related DNF yet! Though Hamilton did start last in China due to qualifying problems.
