I would say the Giants. The Cowboys haven't done any good in December and January since 01. The Steelers have lost 5 in a row, with 3 of them being losses to teams that have less than 4 wins. So I'd say the Giants are doing the best so far.

Though the Dallas Cowboys are a good team, the Pittsburgh Steelers are a better team, because the Steelers have won the most Superbowl's out of any other team in the NFL, over a period of time when the team was first established to the present day.
According to Pro Football Reference, including the postseason, the Dallas Cowboys lead the all-time series, 16-15.
