to suggest they aren't a par defensively is ridiculous.
their defesive point shares are extremely close.
Not to mention that FauxCentre on Twitter who is part of the analytics team for the Kingston Frontenacs (who i would assume has resources available that most people wouldn't) had them on par defensively as well.

I don't know why you keep posting this guy's charts as if they mean anything. They don't. It has already been explained to you that this is entirely the subjective opinion of one person on Twitter who has gone out of his way on multiple occasions to
clarify this subjectivity. Citing his subjective opinions is not citing valid evidence to support your stance but rather making an appeal to authority argument.
Additionally, we don't even know what type of analytics he does for Kingston. Based on what I've heard from similar people in similar positions, it's very likely that they just have him tracking micro stats. But regardless of what he does, it's extremely unlikely that the additional resources possessed by the Kingston Frontenancs - an OHL team - even have any relevance to whether or not Pettersson or Matthews is the superior defensive player. Moreover, even if they did, it would be very unlikely that they would provide this kid with those resources.
Citing his opinion is meaningless. It would be no different than citing somebody on one of the prior pages that said "Pettersson is far better defensively AINEC." In order for those charts to provide value, they'd need to either provide objective evidence (they don't) or he'd need to go into much better detail on the subjective side of things. His defensive analysis on Matthews literally boils down to "Great in zone coverage in all areas" and "Good with stick checks" while his analysis on Pettersson literally boils down to "Great in-zone defense," "Good with stick," and "Keeps puck away from net." You could put together a Python script that does a better job of writing vague statements about their defensive capabilities than this guy did.
Defensive point shares are a joke. Alex Goligoski is a terrible defensive player and he finished 9th in defensive point shares this season. Pettersson and Matthews' 1-year and 3-year RAPM charts charts both depict Pettersson as the significantly superior defensive player:
