I'd go

1) 3
2) 1
3) 4
4) 2

Matthews is probably the third-best center there, but Kuch and Bread are likely the best wingers.

Mcdavid is the best player in the league and I'm a huge fan of Stone.

Eichel is very good, and Marchand is a top 3-4 winger in the league IMO, and Pasta isn't too far behind.

Mack is great, but Kane and Ovi aren't as good as they used to be (and therefore aren't as good as guys like Stone, Marchand, Kich, Bread)

Matthews line first (no, I'm not biased. I'm basing it off the fact Panarin and Kuch are on his wings).
McDavid line next I guess.
Then the Mackinnon line.
Last the Eichel line.

Very tough, but I'll go:

3 (Two highest 5v5 assist getters over the last two years on the wings of the best 5v5 goal scorer in the league, they also both have a scoring touch of their own)
4 ( 4 and 1 to me are interchangeable, McDavid with two players that good will obviously form a fantastic line, and Marchand + Pastrnak already form two thirds of the best line in hockey, just swapping one great C for another)
1( See above)
2 (Another great line, just my least favorite of the 4)

For me: it’s a toss up between 2 & 3 for the top spot and 2nd, then 1, then 4.

2, 1, 3, 4.

Line two has the most diversity between speed, power, playmaking.

Line 3 is 100% offense im curious how good they'd actually be in the playoffs. None of really hustle for defensive plays. Matthews maybe.

If you insert Bergeron in Line 4...it would be better.

McDavid is the best player in the NHL. Thats a wild card. Maybe them 1st, but Mac is close enough for me to give line 2 the edge.
