I think it is Kucherov as he has the best per game season of the rest but you can make arguments for any of them while the gap between McDavid and the rest is mammoth. That is significant as the other players here all have incredible peak seasons. I’ll leave Makar out as I treat d men differently. If you adjust to the NHL’s historical league average of 2.24 even strength goals, 0.72 powerplay goals, and 0.10 shorthanded goals these are the results you get for each players three best full seasons by ppg
