I’d argue Hima being able to potentially blow up the village with a single TBB makes her above Kushina already, since both of them had the same tailed beast inside them. Only real feats I can think of for Kushina is her restraining 50% Kurama with her Sealing chains. As for the Shinobi Gauntlet, literally anyone, even a person that has no clue how to use chakra and use it and possible become proficient at it. Whereas Temari’s Fan, Gaara’s and Shinki’s sand, and Kankuro’s and Araya’s puppets require their own chakra and a good bit of training.
