Her claws are pretty good. We don't see her use it again say Reiner's armor, but she pierces the walls of Utgard Keep pretty well, which the other Titans her size are unable to do (or they probably would have to get at the juicy humans inside).

But it would be weird if only the Galliard family could have powerful jaws since it would make the Titan useless in the hands of anyone else. That's true of the Founding, but the Jaw Titan isn't on the same level of special.

Maybe Ymir did have the ability as far as sheer biting/piercing power went even if her physical jaw didn't have the appearance.
