There are 5 GX attacks that beat Brave Blade but on average requires two more energy with 2 of them requires double the energy juts to exceed it's output. Mind you these are one time use attack. When compared to VMax which are all stage 1, Lapras VMax is the only one that beats Zacian with 3 energy and can do 270 is all energy is water. Brave Blade is the most efficient attack in the game when comapring energy to damage output and Zacian V is a basic pokemon.
