Note: does anyone think Gretzky wouldn't have easily 1000+ goals if he didn't almost always look for the pass first?
I think a good example of that is Gretzky powerplay scoring vs even strength and shorthanded.
On EV-SH, things happen, chaotic, maybe there is no one to pass it to right now, but Gretzky strong skating, anticipation, will, quickness he create a shot for himself. even more in SH situation.
On the power play there is always a good pass play possible, he can go behind the net and remove his shots becoming a pure quaterback, etc.... And a lot of shot are a decision over passing it in that scenario and vice-versa.
From 82 to 87 Gretzky scored 105 more goals than Bossy but they scored about exactly the same amount on the powerplay (88 to 85) or Dionne (84). Gretzky did not even lead the league in power play goal, Kerr, Goulet, Ciccarelli scored more.
We can imagine that unlike the other situation, big power play player ice time was more similar to Wayne as well.
