Voted EP afte changing my vote from Barzal. But if I could do it again I'd vote too close to call.
Barzal is proven. He's also older. He's clearly a better skater. He's stronger. But he is more of a playmaker than anything else. (not that there's anything wrong with that)
EP clearly has a better shot, while still being an elite playmaker. He's also younger, but not as good a skater and not as strong yet. His hockey sense is special.
I haven't seen enough of Barzal to say if he's better or worse defensively, but EP is already a strong defensive player. I think most weren't expecting his defensive game to be as far along as it is already.
Its hard to compare since EP hasn't played a full season yet, but he does look like a special player. Only advantage EP has right now is that he's ahead of where Barzal was as a teenager. Otherwise its really hard to argue against the more proven Barzal. Hence his lead.
Going forward? I think too close to call. This will be an interesting one to revisit at the end of the season.
