IMO, the difference between Matthews and Mackinnon in the regular season is a small enough gap it can be argued either way. However, they're both playing on cup contenders now, the regular season doesn't really matter. Moving forward, it would be impressive if Matthews hit 60 goals or Mack hit 110 points, but it wouldn't be a gamechanger for how I view them. Mack has shown he elevates his game in the playoffs and flat out dominates at times, to the point that there were talks that people would take Mack over McDavid (who is obviously better). Matthews needs to show he can elevate his game in the playoffs and be a gamebreaker.
