Whether a Quirk or any ability is powerful or 'sucks' depends on how a person learns to use it. Admittedly, when people hardly can learn to use it, certain types won't get out of the category of 'sucks.' Dabi isn't the person to convince of most these matters. They also aren't back in his universe. Honestly, Mayerling isn't terribly interested in going there. Undoubtedly being a vampire would be labeled as a Quirk, and his very existence would be a crime. Not much difference, perhaps, save that he doesn't need a new environment for that.

"Pray tell, what is the person with four extra arms expected to do their whole life?" Mayerling asks, "Hang them at their sides? Hold them across their body like a prisoner?" No, the answer is to be a hero, but people simply want to live.

"They'd be better off teaching someone who can control the weather how to improve the climate, for agriculture, for maintaining the planet, and so forth, than only for crime and natural disasters. They could stop disasters before they happened," he says. "Someone who could disintegrate things could readily dispose of nuclear waste. There's better use of Quirks than their limits.

"I agree, of course, that it should be someone's choice to use their Quirks. Held to the same moral and legal standards as any other. Murder is murder. You don't need a special law about Quirks to consider it illegal whether done by bare hands without powers or with six."
