Laine and Vanek have almost identical paces through their age 26 seasons:
-Vanek: 172 goals and 313 points in 389 games, pace of 36 goals and 66 points per 82 games
-Laine: 204 goals and 388 points in 480 games, pace of 35 goals and 66 points per 82 games
I think career has to go to Vanek since he played well into his mid 30s while Laine seems to be a question mark going forward. Vanek maintained that same 35 goal, 65 point level through his age 30 season while also staying very healthy. Laine would need to bounce back to his old form and play another 3-4 seasons at that level and another 3-4 seasons at a solid 50 point level for him to match Vanek's career.
For peak, I think the two had such indistinguishable production that you can't go wrong either way. I think Vanek's 2006-2007 (43 goals and 84 points) was the best season, but Laine could have matched that in both 2019-2020 and 2021-2022 had COVID not existed and he stayed healthy.
