Winterpark has more snow than Breck right now by almost 100". This time of year it also tends to benefit from both upslope and easterly flowing storms. So if you are going by amount of snow, Winterpark is a better bet.
Breck has more sunny aspects though, as much of Winterpark is well below treeline. The tree riding is top 3 in the state at Winterpark, but tree riding is not so hot late season unless it dumps. So for ripping corn harvest turns, Breck is probably going to be better.
