For me there is no debate to have.. Domi is clearly a better player than Galchy. Even next year if Galchy finish with 85 pts and Domi 70 I would still think we get the besf out of this deal. While Galchenyuk have a crazy shot, he can also be invisible for some periods or worst try to complexify the game and at all time he's terrible defensively and lacks attitude and desire to win. Domi is fast, skilled and play with emotion every night. And tonight was a good proof of how he is a proud competitor when he created a turnover and then on the same play he end up scoring or passing for a goal (don't remember since he had a not so bad 5 pts game night!!). He doesn't back down in front of anyone too and he seems to be appreciate in the locker.
For me Domi is like a mix between Gomez, Koivu and his dad all in a single player... the speed and puck control of Gomez.. the leadership, passing skills and emotion of Koivu and the grit and attitude of his dad. He just doesnt have the fighting skills of his dad and even that I'm not sure as he might have lol.
If Drouin could show some more consistency in his play, I could see Domi finishing between 75-80 pts this season.
