The only thing Sid has on ovey is being canadian and therefore more international success. The ppg record is pretty weak when it includes like 6 seasons under 80 points.
The only thing Crosby has over OV is being a better player over his career on a more consistent basis.
OV is top 10 for sure but he disapeared from the NHL best player discussions in 2011, 2012, 2014, 2016, 2017.
That is 5 years in his entire prime he wasnt a top 5/10 player leaguewide
He became a pure goal scorer who won the rocket 9 times. But his hart votes and ross finishes over those 9 rockets come mainly from his small prime period of 2008-2010.
After that he was trailing Crosby for the next 7/8 years where Crosby was routinely being discussed as best player in the NHL who got hurt by his 3 year prime missed due to injuries
2006 - 2010
OV has 269G + 260A =529 (1st in league) pts in 396 games +65 and 1.34ppg (2nd in league)
Crosby has 183G + 323A = 506 pts (3rd in league) in 371 games +45 = 1.36 ppg (1st in league)
This period OV is better season by sesson and over 5 year cumulative period he is minimally behind in ppg while being an elite play driver and offense driver woth strong +/-.
2011 - 2017 stretch
OV has 289G + 217A =506 (3rd in league) pts in 525 games +20 and 0.96ppg (6th in league)
Crosby has 199G + 322A = 521 pts (2nd in league) in 411 games +120 = 1.27 ppg (1st in league)
This period OV vs Crosby comparison dies. Crobsy is better by a wide amount season by season and over 6 year cumulative period he is a lot behind in ppg while being reduced as a play driver and offense driver with weak +/- and 5v5 impacts despite winning 4 rockets here. Crosby after 5 years of being 2nd best player in the league in a total basis from 06 to 10 steps up and is clear cut best player in the league by a fairly signifcant margin for next 7 years.
2018 - 2025
OV has 337G + 248A =585 (17th in league) pts in 567 games -24 and 1.03ppg (20th in league)
Crosby has 241G + 415A = 656 pts (9th in league) in 567 games +31= 1.27 ppg (11th in league)
This period crosby is still the better player overall but OV narrows the gap from previous 7 year period and makes it closer with 3 more rockets won. Ov remains a pure goal scorer and limited play driver and offense driver this period especially vs Crosby.
If you look over these three perods their ranks as players league wide would be
2006-2010: OV = 1st, Crosby = 2nd
2011-2017: OV = 4th-6th, Crosby = 1st
2018-2025: OV = ~15th, Crosby=, ~10th
Crosby has the all time consistency in production with him being a top ~10 player in his 30s in the league. OV's consistency in goal scoring makes him the GOAT goal scorer but he had to adapt to that style as his prime self was lost and he couldnt keep up with the very best players in the league from 2011 onwards while Crosby maintained that standard until 2017ish
