I can understand why people are voting Domi, but for me, on my team...i'd take DeBrusk between the two, pretty easily.
The way i see it, DeBrusk (brutal season aside), is effectively a ~20G - 40ish Pt Winger, who can bring a lot of hustle and energy, along with decent size. He's got the makings of a solid complementary winger who can slide up and down your Top-9. Even if the raw skill just isn't there for a particularly high "absolute ceiling", or true line-driving impact.
Whereas Domi may have the slightly higher "ceiling" offensively in a situation where he's given the opportunity to really run free. But for the most part, in a comparable role he's effectively a ~10-15G - 45ish Pt Winger who wants to play Center. It makes him one of those kind of "awkward fit" guys for me. In that, i think he's better suited to playing up the lineup in a prime offensive role as more of a "play driver" and "focal point" of a line, and probably playing center to boot. That's where you get "the most" out of him and where his contributions really make sense. But he's not quite good enough to actually satisfactorily and reliably fill that role on a strong team as a "key player".
So in terms of slotting in as that "Complementary Top-9 Winger"...the points are close enough to a wash in that role, i prefer what DeBrusk brings to the table as an all-around package. Between the more goal-scoring skewed production, and the ability to make an impact outside the score sheet. The hits, energy, hustle, and even ability to maybe kill the odd penalty, are more desirable in that role for me, than maybe eeking another half dozen assists out of the season. Which just becomes even more true, the further you push the two down the lineup.
In short: Domi might be the "better" Top-6 Center in a vacuum. But when he's not actually good enough in that role, it's kind of a moot point. Where DeBrusk is the "better" player, and the one i'd prefer in the role that i'd actually hope to have either of them play on a strong, competitive team.
