I would have no ground to judge Conacher vs peak Richard vs Bobby Hull, modern day my feeling would be Mario, but unlike Gretzky playmaking or Orr for 2 way defenseman play, no one really stand out enough to say.
Number wise career last time I looked it, would be around
Ovechkin
Richard
Lemieux
Hull and hull
When talking peak, Gretzky-Matthews-Bure would enter the conversation, for 2 others to round it to 10, Bossy-Selanne maybe, Esposito scored a lot and hard to keep out but so did Jagr, those 2 can be a bit underrated as goalscorer specially Jagr.
