Forsberg is the best all around player right now, but is a couple years older. I take 21 year old Pastrnak over 21 year old Forsberg. I think I take Pasta going forward because I think he will continue to be better than Forsberg at each age, but I'm a Bruins fan, so not sure if I am being as objective as I am trying to be.
edit: I see from the voting I am not the only one that views it as a tough call.
