I don't remember Sutton ever having anything like the dynamic ability of Zaddy. As a skater, goal-scorer, or honestly even as a hitter or physical presence. Zadorov has games, or parts of games where he looks like a #1D for a shift. Then others where he looks like Luca Sbisa.
Sutton always struck me as a lot more consistent, but meh.
Generally agree that Zadorov has shown more flashes of high level play, but they’re just flashes. Zadorov is 28. He is what he is at this point. That’s a guy with a 22 point career high. I think overall his presence and usage is similar to Sutton’s (ideally third pair but can be second pair with ideal partner).
I think you may be forgetting how physically imposing and aggressive Sutton was. He played with the most disregard for other’s safety I’ve seen from the sens. These are all from one season:
(The video being age restricted somewhat says it all)
If you’re reading a Sutton comparison as a negative, it’s really not, I like both players and would gladly add either to my team.
