I am talking about a Fuji vs shiki fight. Fuji just have the better one. Fuji have full controll of gravity. He can even create horizontal gravity.
That being said, i am not saying Shikis DF is weak or anything. Fuji just should be able to counter it better than Shiki. Shiki can't stop a meteor with his DF, he had to touch it - but hard to imagine lol. Sure he can use the ground or whatever, but this is not the point. Fuji can just blast everything away what Shiki sends to him, without even touching it.
The water thing doesn't make sense imo and was always weird to me tho. If this was even canon?
But even when Shiki can control water, Fujitora can just push it away.
