Mason gets a 3 for JoJolity. While somewhat effective for rational people, these people aren't exactly rational, and are kiinda under a Stand effect. And besides, who's to say the chaos he creates won't just make the people panic more?

and DJ gets a solid 8 for JoJolity. It's a bit brutal for my tastes, but it definitely gets the job done, with a slight panic boost at the start, yet a brutal, quick pacification of the population. It also works in DJ's favor when it comes to Dr. Mason, along with the objective. Dropping chandeliers is... crude, but honestly works when trying to pacify a crowd fast.

For Quality, Dr. Mason gets a 4. He puts up a decent fight against DJ, and I think they'd be roughly even, however he barely pays any focus to the actual objective of the map, giving it a cursory glance where he's not likely to spot it in the position he's in.

DJ gets a 8 (again), because he puts more focus on the objective and has, what I believe, is the better fight strategy. Dr. Mason kinda underestimated Rasputin and overestimated his own ability, while DJ takes few precautions besides a slight underestimation of Dark Side's ability.

I'll start with JoJolity first.

Mason gets a 10. Cutting visibility will cause some panic, but they won't be fighting each other. Also, by causing sprinklers to activate, he's getting all of them wet, and they'd be evacuating the building, effectively emptying the room. Most importantly, he's going about this by not hurting anyone.

DJ gets a lower 3 in my opinion. I'm really not a fan of his brutal way of achieving JoJolity. While the level-headed DJ can knock them out, it just seems pretty counter productive to me. "Let's stop the riot by participating in the riot!" Not to mention, the civilians are in the end, wild cards, and seems to go against the point of being a bodyguard.

Now the actual quality.
In this one, DJ got the higher quality strategy. Earning him the full 10 in my opinion, while Mason nets a 7. Both are well-written strategies, and can plausibly see both working quite well.

In short, for Jojolity, I believe Mason gets it, merely because I felt like DJ's tactics of cutting down the chandelier and reducing light, then in general wreaking chaos against the good doctor, is likely to cause more panic, making subduing it hard. However, in terms of the actual fight, DJ wins. He predicted a lot of Mason's strategies and gave great arguments for resisting and outright conquering them.

On a scale of 1 to 10... Mason got a 5 out of 10 in Jojolity, and DJ got a 7 out of 10 in Quality.
DJ gets a 2 out of 10 in Jojolity, and Mason gets a 5 out of 10 in Quality
