Not a homer for either team, but I think it's silly to have this discussion right now. Think back over the past 15 years and imagine how many twists and turns the Brady vs. Manning debate has had. Sure, looking back on it now, it would be hard to argue that Brady didn't ultimately "win", but you might have gotten different answers in 2004, 2006 and 2013.
The fact that Wentz is so far ahead in the voting is largely a function of the Eagles being 9-1 and having just destroyed Dallas last night. We have no idea where the two of these guys will be two, five or ten years from now.
