Crosby is a beast, no doubt. As I detailed in that post he is clearly declining faster and not as durable as Kopi. He also is used in a much more offensive role. 65/35 Ozone vs Dzone starts. Compared to Kopis 54/46 split. He also gets to play on a pp unit with Malkin (the other generational offensive talent) Guentzel, Letang, etc...
Kopitar is asked to do much more on the defensive side of the puck (hopefully nobody argues that), he's played on a team that has always had a more defensive system. And especially once you get on the pp he has for sure had significantly less offensive talent to work with.
Kopitar has led a team that won two Stanley cups in scoring 13 times (I'm honestly not sure how many players in NHL history have ever carried a team offensively so consistently over such a long stretch.) Crosby has led a team that won three Stanley cups in scoring 11 times.
Almost nobody outside of Kings fans would say that Kopitar is on the same level as Crosby. So you can take the win with that argument and keep circling back to ppg, media, and awards. But I'm a Kings fan and don't really care if it comes across as biased (which it probably is!) To me, Kopitar is just as good as Crosby, Ovechkin, Malkin, Kane, etc... he just does it in a different way that will never receive the type of respect as the ppg crew of his era. (Kopitar ppg is pretty beast anyways, 16th among active players)
