Mac and it's not close. You forgot to factor in games played. MacKinnon only played 44 games
MacKinnon was also at 1.92 PPG in the playoffs.
Hischier only got 7 points in 6 games.
1.
Halifax Mooseheads 2016-17 (with Hischier): 27-35-3-3, a .441% percentage.
Halifax Mooseheads 2012-13 (with McKinnon): 58-6-3-1, a .882% percentage.
Those percentages, translated to an NHL style 82 games season would translate into a team getting 72 points vs a team getting 144 points.
McKinnon's Mooseheads scored 347 goals that season (goal differential... +171). Nico's Mooseheads? 229 (goal differential -30)...
Did you know that Nico had a +/- of +20 (lead the whole team, lead all rookie forwards), while the best forward after him had a... 0? It's not even funny how Nico had to literally drag his team all by himself.
2. That was McKinnon 2nd year in the Q + he played all his life on NA ice. This was Hischier first season in the Q and first in North America.
3. Hischier got a wrist injury that limited him on the latter part of the season. I don't know if McKinnon was playing hurt too. If anyone knows, please do tell.

So, in this comparison, are you that sure that the playing field was even remotely close to level, to express such a judgement? What Nico achieved for that team is pretty much a miracle. Nico's season was much more difficult to achieve than McKinnon, given the conditions.
