It doesn't matter what you care or don't care about.
Gretzky and Lemieux played at a level far above anyone the league had ever seen before or since from an offensive production standpoint.
An aging, broken Lemieux was still neck-and-neck with a prime Jagr as the NHL entered the dead-puck era. Eventually, Jagr became the league's best offensive player. A 33-34 year old Jagr scored 123 points in the 2005-2006 season with the New York Rangers - which coincidentally is Sidney Crosby's rookie year. In 2006-2007, Crosby's highest scoring year, he scored 120 points. In the last few years, a young closer-to-his-prime McDavid has been beating an aging Crosby for Art Ross trophies, and in his best years might score in the 120-130 range as did Jagr and Crosby. Jagr, Crosby, and McDavid are a lot closer in overall offensive capability than they are to Gretzky and Lemieux, who are head and shoulders above the rest. In the 60's and 70's, before Gretzky came along, no one would have believed a player could score over 200 points in a season, and no has done it since.
You see, you might have had a case if these eras had existed in a vacuum, but they didn't. There is/was overlap. McDavid is in the middle of taking over from Crosby, who took over from Jagr. And none of these three were anywhere near close to Gretzky and Lemieux.
It's not an opinion.
You just can't win this one.
