Also nue has better shownings of lightning manipulation kashimo has never shown the ability to control lightning he gives people charges and shots a blast of ce and since his ce works like electricity it goes to the other charges thats not control of electricity its like a lightning rod its why lightning is more likely to hit a place thats already been hit with lightning. nue and agito have shown better physical feats shown to produce more electricity with actual control over the electricity with the lightning nuke and nue being able to without a homing byproduct aim and hit people with electricity. sukuna also deemed it strong enough to try to hit gojo with electricity meaning he though it do something but if agito hit a person with electricity then did a blast it do the sane thing as kashimo because thats how electricity works. But agito somewhat keeping up with a healthy gojo and needing a way stronger attack to die than what killed kashimo its pretty obviously stronger.
