Las Vegas is much the better team. I want the Golden Knights going for me, too, after they suffered a disappointing 4-3 loss at home to the Bruins. 
Arizona is 0-2 on the season. The Coyotes ranked third-from-the-bottom in scoring last season. They have scored one goal this season. 
The Golden Knights have never lost at Arizona going 4-0 versus the Coyotes on the road, winning those games by a combined seven goals.
